GENERAL DESCRIPTION
The OP470 is a high-performance monolithic quad operational
amplifier with exceptionally low voltage noise, 5 nV/X/ Hz at
1 kHz Max, offering comparable performance to ADI’s industry
standard OP27.
The OP470 features an input offset voltage below 0.4 mV,
excellent for a quad op amp, and an offset drift under 2 mV/C,
guaranteed over the full military temperature range. Open loop
gain of the OP470 is over 1,000,000 into a 10 kW load ensuring
excellent gain accuracy and linearity, even in high gain applica-
tions. Input bias current is under 25 nA, which reduces errors
due to signal source resistance. The OP470’s CMR of over
110 dB and PSRR of less than 1.8 mV/V significantly reduce
errors due to ground noise and power supply fluctuations.
Power consumption of the quad OP470 is half that of four
OP27s, a significant advantage for power conscious applica-
tions. The OP470 is unity-gain stable with a gain bandwidth
product of 6 MHz and a slew rate of 2 V/ms.
The OP470 offers excellent amplifier matching which is important
for applications such as multiple gain blocks, low noise instrumen-
tation amplifiers, quad buffers, and low noise active filters.
The OP470 conforms to the industry standard 14-pin DIP pinout.
It is pin compatible with the LM148/149, HA4741, HA5104,
and RM4156 quad op amps and can be used to upgrade systems
using these devices.
For higher speed applications, the OP471, with a slew rate of
8 V/ms, is recommended.

NOTES
1Absolute Maximum Ratings apply to both DICE and packaged parts, unless
otherwise noted.
2The OP470’s inputs are protected by back-to-back diodes. Current limiting
resistors are not used in order to achieve low noise performance. If differential
voltage exceeds ± 1.0 V, the input current should be limited to ± 25 mA.
3jA is specified for worst case mounting conditions, i.e., jA is specified for device
in socket for TO, CerDIP, PDIP, packages; jA is specified for device soldered to
printed circuit board for SO packages.

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 OP470 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.
