GENERAL DESCRIPTION  
200µs/DIV  
500mV/DIV  
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.ꢀ 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 20 mV of each rail for IOUT ≤ 100 μA, providing  
outstanding output dynamic range. It also has a linear output  
current of 40 mA, 0.ꢀ V from the supply rails.  
Figure 3. Output Swing, +VS = +3 V, G = +1  
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 +8ꢀ°C and is offered in an 8-lead SOIC package and  
an 8-lead MSOP package.  
An offset voltage of 700 μV maximum, an offset voltage drift of  
1 μV/°C, and typical input bias currents of 0.3 pA provide dc  
precision with source impedances up to 1 GΩ. The AD823A  
provides 17 MHz, −3 dB bandwidth, and a 30 V/μs slew rate with  
a low supply current of only 2.6 mA per amplifier. It also provides  
low input voltage noise of 14 nV/√Hz and −108 dB SFDR at  
20 kHz. The AD823A has low input capacitances (0.6 pF differ-  
ential and 1.3 pF common mode) and drives more than ꢀ00 pF  
of direct capacitive load as a follower. This lets the amplifier  
handle a wide range of load conditions.
