The AD704 is a quad, low power bipolar op amp that has the
low input bias current of a BiFET amplifier but which offers a
significantly lower IB drift over temperature. It utilizes super-beta
bipolar input transistors to achieve picoampere input bias current
levels (similar to FET input amplifiers at room temperature),
while its IB typically only increases by 5× at 125°C (unlike a
BiFET amp, for which IB doubles every 10°C resulting in a
1000× increase at 125°C). Furthermore, the AD704 achieves
75 µV offset voltage and low noise characteristics of a precision
bipolar input op amp.

Since it has only 1/20 the input bias current of an AD OP07, the
AD704 does not require the commonly used “balancing” resistor.
Furthermore, the current noise is 1/5 that of the AD OP07 which
makes the AD704 usable with much higher source impedances.
At 1/6 the supply current (per amplifier) of the AD 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 and is available in five
performance grades. The AD704J and AD704K are 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
AD704T is rated over the military temperature range of –55°C
to +125°C and is available processed to MIL-STD-883B, Rev. C.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD704 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

The instrumentation amplifier circuit offers many performance
benefits including BiFET level input bias currents, low input
offset voltage drift and only 1.2 mA quiescent current. It will
operate for gains G ≥ 2, and at lower gains it will benefit from
the fact that there is no output amplifier offset and noise contri-
bution as encountered in a 3 op amp design. Good low frequency
CMRR is achieved even without the optional ac CMRR trim
(Figure 4). Table I provides resistance values for 3 common
circuit gains. For other gains, use the following equations:

The 1 Hz, 4-pole active filter offers dc precision with a minimum
of components and cost. The low current noise, IOS, and IB
allow the use of 1 MΩ resistors without sacrificing the 1 µV/°C
drift of the AD704. This means lower capacitor values may be
used, reducing cost and space. Furthermore, since the AD704’s
IB is as low as its IOS, over most of the MIL temperature range,
most applications do not require the use of the normal balancing
resistor (with its stability capacitor). Adding the optional balancing
resistor enhances performance at high temperatures, as shown in
Figure 5. Table II gives capacitor values for several common low
pass responses.

Specified values are for a –3 dB point of 1.0 Hz. For other frequencies, simply scale capacitors C1 through C4 directly; i.e., for 3 Hz Bessel response, C1 = 0.0387 µF,
C2 = 0.0357 µF, C3 = 0.0533 µF, C4 = 0.0205 µF.
