The ADA4622-1/ADA4622-2/ADA4622-4 are the next generation of the AD820/AD822/AD824 single-supply, rail-to-rail output (RRO), precision junction field effect transistors (JFET) input op amps. The ADA4622-1/ADA4622-2/ADA4622-4 include many improvements that make them desirable as upgrades without compromising the flexibility and ease of use that makes the AD820/AD822/AD824 useful for a wide variety of applications.The input voltage range includes the negative supply and the output swings rail-to-rail. Input EMI filters increase the signal robustness in the face of closely located switching noise sources.The speed, in terms of bandwidth and slew rate, increases along with a strong output drive to improve settling time performance and enables the devices to drive the inputs of modern single-ended, successive approximation register (SAR) analog-to-digital converters (ADCs).Voltage noise is reduced; although the supply current remains the same as the AD820/AD822/AD824, broadband noise is reduced by 25%, and 1/f is reduced by half. DC precision in the ADA4622-1/ADA4622-2/ADA4622-4 improved from the AD820/AD822/AD824 with half the offset and a maximum thermal drift specification added to the ADA4622-1/ADA4622-2/ADA4622-4. The common-mode rejection ratio (CMRR) is improved from the AD820/AD822/AD824 to make the ADA4622-1/ADA4622-2/ADA4622-4 more suitable when used in noninverting gain and difference amplifier configurations.The ADA4622-1/ADA4622-2/ADA4622-4 are specified for operation over the extended industrial temperature range of −40°C to +125°C, and operate from 5 V to 30 V, with specifications at +5 V, ±5 V, and ±15 V.

The ADA4805-1 is a high speed voltage feedback rail-to-rail output amplifier with an exceptionally low quiescent current of 495 μA, making it ideal for low power, high resolution data conversion systems. Despite being low power, this amplifier provides excellent overall performance. It offers a high bandwidth of 105 MHz at a gain of 1, high slew rate of 160 V/μs, and a low input offset voltage of 125 μV maximum.A shutdown pin allows further reduction of the quiescent supply current to 3 μA. For power sensitive applications, the shutdown mode offers very fast turn-on time of 3 μs from shutdown to fully on (output settled to 16 bits). This allows the user to dynamically manage the power of the amplifier by turning the amplifier off between ADC samples.The Analog Devices, Inc., proprietary extra fast complementary bipolar (XFCB) process allows for both low voltage and low current noise (5.9 nV/√Hz, 0.6 pA/√Hz).

The ADA4806-1 is a high speed, voltage feedback, rail-to-rail output, single operational amplifier with three power modes: full power mode, sleep mode, and shutdown mode. In full power mode, this amplifier provides a wide bandwidth of 105 MHz at a gain of +1, a fast slew rate 160 V/μs, and excellent dc precision with a low input offset voltage of 125 μV (maximum) and an input offset voltage drift of 1.5 μV/°C (maximum), while consuming only 500 μA of quiescent current. Despite being a low power amplifier, the ADA4806-1 provides excellent overall performance, making it ideal for low power, high resolution data conversion systems.For data conversion applications where minimizing power dissipation is paramount, the ADA4806-1 offers a method to reduce power by dynamically scaling the quiescent power of the ADC driver with the sampling rate of the system by switching the amplifier to a lower power mode between samples.Sleep mode reduces the amplifier quiescent current to 74 μA and provides a fast turn-on time of only 0.45 μs, enabling the use of dynamic power scaling for sample rates approaching 2 MSPS. For additional power savings at lower samples rates, the shutdown mode further reduces the quiescent current to only 2.9 μA.The ADA4806-1 operates over a wide range of supply voltages and is fully specified at supplies of 3 V, 5 V and ±5 V.

The AD600/AD602 dual channel, low noise, variable gain amplifiers are optimized for use in ultrasound imaging systems, but are applicable to any application requiring precise gain, low noise and distortion, and wide bandwidth. Each independent channel provides a gain of 0 dB to +40 dB in the AD600 and -10 dB to +30 dB in the AD602. The lower gain of the AD602 results in an improved signal-to-noise ratio (SNR) at the output. However, both products have the same 1.4 nV/√Hz input noise spectral density. The decibel gain is directly proportional to the control voltage, accurately calibrated, and supply and temperature-stable.To achieve the difficult performance objectives, a proprietary circuit form, the X-AMP®, was developed. Each channel of the X-AMP comprises a variable attenuator of 0 dB to -42.14 dB followed by a high speed fixed gain amplifier. In this way, the amplifier never has to cope with large inputs, and can benefit from the use of negative feedback to precisely define the gain and dynamics. The attenuator is realized as a 7-stage R-2R ladder network having an input resistance of 100 W, laser trimmed to ±2%. The attenuation between tap points is 6.02 dB; the gain-control circuit provides continuous interpolation between these taps. The resulting control function is linear in dB.The gain-control interfaces are fully differential, providing an input resistance of ~15 M W and a scale factor of 32 dB/V (that is, 31.25 mV/dB) defined by an internal voltage reference. The response time of this interface is less than 1 µs. Each channel also has an independent gating facility that optionally blocks signal transmission and sets the dc output level to within a few millivolts of the output ground. The gating control input is TTL- and CMOS-compatible.The maximum gain of the AD600 is 41.07 dB, and the maximum gain of the AD602 is 31.07 dB; the -3 dB bandwidth of both models is nominally 35 MHz, essentially independent of the gain. The SNR for a 1 V rms output and a 1 MHz noise bandwidth is typically 76 dB for the AD600 and 86 dB for the AD602. The amplitude response is flat within ±0.5 dB from 100 kHz to 10 MHz; over this frequency range, the group delay varies by less than ±2 ns at all gain settings.Each amplifier channel can drive 100 W load impedances with low distortion. For example, the peak specified output is ±2.5 V minimum into a 500 W load, or ±1 V into a 100 W load. For a 200 W load in shunt with 5 pF, the total harmonic distortion for a ±1 V sinusoidal output at 10 MHz is typically -60 dBc.The AD600J/AD602J are specified for operation from 0°C to 70°C and are available in 16-lead PDIP (N) and 16-lead SOIC packages. The AD600A/AD602A are specified for operation from -40°C to +85°C and are available in 16-lead CERDIP (Q) and 16-lead SOIC packages. The AD600S/AD602S are specified for operation from -55°C to +125°C, are available in a 16-lead CERDIP (Q) package, and are MIL-STD-883 compliant. The AD600S/AD602S are also available under DESC SMD 5962-94572.AD600 - Gain Range: 0 dB to 40 dBAD602 - Gain Range: -10 dB to + 30 dB

The AD627 is an integrated, micropower instrumentation amplifier that delivers rail-to-rail output swing on single and dual (+2.2 V to ±18 V) supplies. The AD627 provides excellent ac and dc specifications while operating at only 85 μA maximum.The AD627 offers superior flexibility by allowing the user to set the gain of the device with a single external resistor while con-forming to the 8-lead industry-standard pinout configuration. With no external resistor, the AD627 is configured for a gain of 5. With an external resistor, it can be set to a gain of up to 1000.A wide supply voltage range (+2.2 V to ±18 V) and micropower current consumption make the AD627 a perfect fit for a wide range of applications. Single-supply operation, low power consumption, and rail-to-rail output swing make the AD627 ideal for battery-powered applications. Its rail-to-rail output stage maximizes dynamic range when operating from low supply voltages. Dual-supply operation (±15 V) and low power consumption make the AD627 ideal for industrial applications, including 4 to 20 mA loop-powered systems.The AD627 does not compromise performance, unlike other micropower instrumentation amplifiers. Low voltage offset, offset drift, gain error, and gain drift minimize errors in the system. The AD627 also minimizes errors over frequency by providing excellent CMRR over frequency. Because the CMRR remains high up to 200 Hz, line noise and line harmonics are rejected.The AD627 provides superior performance, uses less circuit board area, and costs less than micropower discrete designs.Applications4 mA to 20 mA loop-powered applicationsLow power medical instrumentation—ECG, EEGTransducer interfacingThermocouple amplifiersIndustrial process controlsLow power data acquisitionPortable battery-powered instruments

The AD711 is a high speed, precision monolithic operational amplifier offering high performance at very modest prices.
