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. This amplifier is available in a compact, 8-lead SOT-23 package and is rated to operate over the industrial temperature range of −40°C to +125°C.Applications Portable and battery-powered instruments and systems High channel density data acquisition systems Precision analog-to-digital converter (ADC) drivers Voltage reference buffers Portable point of sales terminals Active RFID readers

The AD549 is a monolithic electrometer operational amplifier with very low input bias current. Input offset voltage and input offset voltage drift are laser trimmed for precision performance. The ultralow input current of the part is achieved with Topgate™ JFET technology, a process development exclusive to Analog Devices, Inc. This technology allows fabrication of extremely low input current JFETs compatible with a standard junction isolated bipolar process. The 1015 Ω common-mode impedance, which results from the bootstrapped input stage, ensures that the input current is essentially independent of the common-mode voltage.The AD549 is suited for applications that require very low input current and low input offset voltage. It excels as a preamp for a wide variety of current output transducers, such as photo-diodes, photomultiplier tubes, or oxygen sensors. The AD549 can also be used as a precision integrator or low droop sample and hold. The AD549 is pin compatible with standard FET and electrometer op amps, allowing designers to upgrade the performance of present systems at little additional cost.The AD549 is available in a TO-99 hermetic package. The case is connected to Pin 8 so that the metal case can be independently connected to a point at the same potential as the input terminals, minimizing stray leakage to the case. The AD549 is available in four performance grades. The J, K, and L versions are rated over the commercial temperature range of 0°C to +70°C. The S grade is specified over the military temperature range of −55°C to +125°C and is available processed to MIL-STD-883B, Rev. C. Extended reliability plus screening is also available. Plus screening includes 168 hour burn-in, as well as other environmental and physical tests derived from MIL-STD-883B, Rev. C.Product Highlights The AD549 input currents are specified, 100% tested, and guaranteed after the device is warmed up. They are guaranteed over the entire common-mode input voltage range. The AD549 input offset voltage and drift are laser trimmed to 0.50 mV and 15 μV/°C (AD549K), and to 1 mV and 20 μV/°C (AD549J).. A maximum quiescent supply current of 700 μA minimizes heating effects on input current and offset voltage. AC specifications include 1 MHz unity gain bandwidth and 3 V/μs slew rate. Settling time for a 10 V input step is 5 μs to 0.01%. Applications Electrometer amplifier Photodiode preamp pH electrode buffer

The AD582 is a sample-and-hold amplifier consisting of a high performance operational amplifier, a low leakage analog switch and a JFET integrating amplifier – all fabricated on a single monolithic chip. An external holding capacitor, connected to the device, completes the sample-and-hold function.With the analog switch closed, the AD582 functions like a standard op amp; any feedback network may be connected around the device to control gain and frequency response. With the switch open, the capacitor holds the output at its last level, regardless of input voltage.Typical applications for the AD582 include sampled data systems, D/A deglitchers, analog de-multiplexers, auto null systems, strobed measurement systems and A/D speed enhancement.The device is available in two versions: the 'K' specified for operation over the 0 to +70° commercial temperature range and the 'S' specified over the extended temperature range, -55°C to +125°C. All versions may be obtained in either the hermetic sealed, TO-100 can or the TO-116 DIP.Product HighlightsThe specially designed input stage presents a high impedance to the signal source in both sample and hold modes (up to ±12V). Even with signal levels up to ±VS, no undesirable signal inversion, peaking or loss of hold voltage occurs.The AD582 may be connected in any standard op amp configuration to control gain or frequency response and provide signal inversion, etc.The AD582 offers a high, sample-to-hold current ratio: 107. The ratio of the available charging current to the holding leakage current is often used as a figure of merit for a sample and hold circuit.The AD582 has a typical charge transfer less than 2pC. A low charge transfer produces less offset error and permits the use of smaller hold capacitors for faster signal acquisition.The AD582 provides separate analaog and digital grounds, thus improving the device's immunity to ground and switching transients.The AD582 is available in versions compliant with MIL-STD-883. Refer to the Analog Devices Military Products Databook or current AD582/883B data sheet for detailed specifications.
