PRODUCT DESCRIPTION

500mV

200µs

The AD823 is a dual precision, 16 MHz, JFET input op amp

that can operate from a single supply of +3.0 V to +36 V, or

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

50 mV of each rail for I_OUT≤ 100 µA providing outstanding out-

put dynamic range.

Figure 1. Output Swing, V_S= +3 V, G = +1

Offset voltage of 800 µV max, offset voltage drift of 2 µV/°C,

input bias currents below 25 pA and low input voltage noise

provide dc precision with source impedances up to a Gigohm.

16 MHz, –3 dB bandwidth, –108 dB THD @ 20 kHz and

22 V/µs slew rate are provided with a low supply current of

2.6 mA per amplifier. The AD823 drives up to 500 pF of direct

capacitive load as a follower, and provides an output current of

15 mA, 0.5 V from the supply rails. This allows the amplifier to

handle a wide range of load conditions.

This combination of ac and dc performance, plus the outstand-

ing load drive capability results in an exceptionally versatile am-

plifier for applications such as A/D drivers, high-speed active

filters, and other low voltage, high dynamic range systems.
