GENERAL DESCRIPTION

The AD704 is a quad, low power bipolar op amp that has the

low input bias current of a BiFET amplifier and offers a signifi-

cantly lower I

input transistors to achieve picoampere input bias current levels

(similar to FET input amplifiers at room temperature), while its

for which I

125°C). In addition, the AD704 achieves 150 μV offset voltage and

the low noise characteristics of a precision bipolar input op amp.

Because it has only 1/20 the input bias current of an OP07, the

AD704 does not require the commonly used balancing resistor.

Furthermore, the current noise is 1/5 that of the OP07, which

makes the AD704 usable with much higher source impedances.

At 1/6 the supply current (per amplifier) of the OP07, the

AD704 is better suited for today’s higher density circuit boards

and battery-powered applications.

The AD704 is an excellent choice for use in low frequency active

filters in 12- and 14-bit data acquisition systems, in precision

instrumentation, and as a high quality integrator. The AD704 is

internally compensated for unity gain stability. The AD704J is

rated over the commercial temperature range of 0°C to 70°C.

The AD704A is rated over the industrial temperature of −40°C

to +85°C. The AD704S is rated over the military temperature

range of −55°C to +125°C, processed to MIL-STD-883B.
