The ADG1408 / ADG1409 are monolithic iCMOS® analog multiplexers comprising eight single channels and four differential channels, respectively. The ADG1408 switches one of eight inputs to a common output, as determined by the 3-bit binary address lines, A0, A1, and A2. The ADG1409 switches one of four differential inputs to a common differential output, as determined by the 2-bit binary address lines, A0 and A1. An EN input on both devices is used to enable or disable the device. When disabled, all channels are switched off.The industrial CMOS (iCMOS) modular manufacturing process combines high voltage complementary metal-oxide semiconductor (CMOS) and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no other generation of high voltage parts has been able to achieve. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.The ultralow on resistance and on resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications where low distortion is critical. iCMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments.PRODUCT HIGHLIGHTS 4 Ω on resistance. 0.5 Ω on-resistance flatness. 3 V logic compatible digital input, VIH = 2.0 V, VIL = 0.8 V. 16-lead TSSOP and 4 mm × 4 mm LFCSP.

The OP07D is a low cost option of the OP07 family with voltage offset performance of 150 µV max. The OP07D is a precision, ultralow offset amplifier. It integrates low power (1.1 mA typical), low input bias current (±1 nA maximum), and high CMRR/PSRR (130 dB). Operation is fully specified from ±5 V to ±15 V supply.The OP07D provides higher accuracy than industry-standard OP07-type amplifiers due to Analog Devices’ iPolar™ process, which supports enhanced performance in a smaller footprint. These performance enhancements include wider output swing, lower power, and higher CMRR (common-mode rejection ratio) and PSRR (power supply rejection ratio). The OP07D maintains stability of offsets and gain virtually regardless of variations in time or temperature. Excellent linearity and gain accuracy can be maintained at high closed-loop gains. The OP07D is fully specified over the extended industrial tem¬perature range of −40°C to +125°C. The OP07D amplifier is available in 8-lead DIP and the popular 8-lead, narrow SOIC lead-free packages.

The OP27 precision operational amplifier combines the low offset and drift of the OP07 with both high speed and low noise. Offsets down to 25 μV and maximum drift of 0.6 μV/°C make the OP27 ideal for precision instrumentation applications. Low noise, en = 3.5 nV/√Hz, at 10 Hz, a low 1/f noise corner frequency of 2.7 Hz, and high gain (1.8 million), allow accurate high-gain amplification of low-level signals. A gain bandwidth product of 8 MHz and a 2.8 V/μs slew rate provide excellent dynamic accuracy in high speed, data-acquisition systems.A low input bias current of ±10 nA is achieved by use of a bias current cancellation circuit. Over the military temperature range, this circuit typically holds IB and IOS to ±20 nA and 15 nA, respectively.The output stage has good load driving capability. A guaranteed swing of ±10 V into 600 Ω and low output distortion make the OP27 an excellent choice for professional audio applications.PSRR and CMRR exceed 120 dB. These characteristics, coupled with long-term drift of 0.2 μV/month, allow the circuit designer to achieve performance levels previously attained only by discrete designs.Low cost, high volume production of OP27 is achieved by using an on-chip Zener zap-trimming network. This reliable and stable offset trimming scheme has proven its effectiveness over many years of production history.The OP27 provides excellent performance in low noise, high accuracy amplification of low level signals. Applications include stable integrators, precision summing amplifiers, precision voltage threshold detectors, comparators, and professional audio circuits such as tape heads and microphone preamplifiers.

The OP285 is a precision high-speed amplifier featuring theButler Amplifier front-end. This new front-end designcombines the accuracy and low noise performance of bipolartransistors with the speed of JFETs. This yields an amplifierwith high slew rates, low offset and good noise performance atlow supply currents. Bias currents are also low compared tobipolar designs.The OP285 offers the slew rate and low power of a JFETamplifier combined with the precision, low noise and low driftof a bipolar amplifier. Input offset voltage is laser-trimmed andguaranteed less than 250 μV. This makes the OP285 useful indc-coupled or summing applications without the need forspecial selections or the added noise of additional offsetadjustment circuitry. Slew rates of 22 V/μs and a bandwidth of9 MHz make the OP285 one of the most accurate mediumspeed amplifiers available.The combination of low noise, speed and accuracy can be usedto build high speed instrumentation systems. Circuits such asinstrumentation amplifiers, ramp generators, bi-quad filters anddc-coupled audio systems are all practical with the OP285. Forapplications that require long term stability, the OP285 has aguaranteed maximum long term drift specification.The OP285 is specified over the XIND—extended industrial—(−40°C to +85°C) temperature range. The OP285 is available inan 8-lead SOIC_N surface mount package. Applications High performance audio Active filters Fast amplifiers Integrators

Rail-to-rail output swing combined with dc accuracy are the key features of the OP495 quad and OP295 dual CBCMOS operational amplifiers. By using a bipolar front end, lower noise and higher accuracy than those of CMOS designs have been achieved. Both input and output ranges include the negative supply, providing the user with zero-in/zero-out capability. For users of 3.3 V systems such as lithium batteries, the OP295/OP495 are specified for 3 V operation.Maximum offset voltage is specified at 300 μV for 5 V operation, and the open-loop gain is a minimum of 1000 V/mV. This yields performance that can be used to implement high accuracy systems, even in single-supply designs.The ability to swing rail-to-rail and supply 15 mA to the load makes the OP295/OP495 ideal drivers for power transistors and H bridges. This allows designs to achieve higher efficiencies and to transfer more power to the load than previously possible without the use of discrete components.For applications such as transformers that require driving inductive loads, increases in efficiency are also possible. Stability while driving capacitive loads is another benefit of this design over CMOS rail-to-rail amplifiers. This is useful for driving coax cable or large FET transistors. The OP295/OP495 are stable with loads in excess of 300 pF.The OP295 and OP495 are specified over the extended indus-trial (−40°C to +125°C) temperature range. The OP295 is available in 8-lead PDIP and 8-lead SOIC_N surface-mount packages. The OP495 is available in 14-lead PDIP and 16-lead SOIC_W surface-mount packages.Applications Battery-operated instrumentation Servo amplifiers Actuator drives Sensor conditioners Power supply control

The OP297 is the first dual op amp to pack precision performance into the space-saving, industry standard 8-pin SO package. Its combination of precision with low power and extremely low input bias current makes the dual OP297 useful in a wide variety of applications.Precision performance of the OP297 includes very low offset, under 50µV, and low drift, below 0.6µV/°C. Open-loop gain exceeds 2000V/mV insuring high linearity in every application. Errors due to common-mode signals are eliminated by the OP297's common-mode rejection of over 120 dB. The OP297's power supply rejection of over 120dB minimizes offset voltage changes experienced in battery powered systems. Supply current of the OP297 is under 625µA per amplifier and it can operate with supply voltages as low a ±2V.The OP297 utilizes a super-beta input stage with bias current cancellation to maintain picoamp bias currents at all temperatures. This is in contrast to FET input op amps whose bias currents start in the picoamp range of 25°C, but double for every 10°C rise in temperature, to reach the nanoamp range above 85°C. Input bias current of the OP297 is under 100pA at 25°C and is under 450pA over the military temperature range.Combining precision, low power and low bias current, the OP297 is ideal for a number of applications including instrumentation amplifiers, log amplifiers, phot-diode preamplifiers and long-term integrators.
