AD823A

17 MHz, Rail-to-Rail FET Input Dual Amplifier
Manufactured by:

Product Details

The AD823A is a dual precision, 17 MHz, JFET input op amp manufactured in the extra fast complementary bipolar (XFCB) process. The AD823A can operate from a single supply of 3 V to 36 V or from dual supplies of ±1.5 V to ±18 V. It has true single-supply capability with an input voltage range extending below ground in single-supply mode. Output voltage swing extends to within 17 mV of each rail for IOUT ≤ 100 µA, providing outstanding output dynamic range.

An offset voltage of 700 µV maximum, an offset voltage drift of 1 µV/°C, typical input bias currents of 0.3 pA, and low input voltage noise provide dc precision with source impedances up to 1 GΩ. The AD823A provides 17 MHz, −3 dB bandwidth, −110 dB THD at 20 kHz, and a 30 V/µs slew rate with a low supply current of 2.6 mA per amplifier. The AD823A drives more than 1000 pF of direct capacitive load as a follower and provides a linear output current of 40 mA, 0.5 V from the supply rails. This lets the amplifier handle a wide range of load conditions.

This combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile ampli¬fier for applications such as ADC drivers, high speed active filters, and other low voltage, high dynamic range systems.

The AD823A is available over the industrial temperature range of −40°C to +85°C and is offered in an 8-lead SOIC package and the 8-lead MSOP package.
