The OP470 is a high-performance monolithic quad operational
amplifier with exceptionally low voltage noise, 5 nV/÷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 applications. The
OP470 is unity-gain stable with a gain bandwidth product of
6 MHz and a slew rate of 2 V/ms.

NC = NO CONNECT
The OP470 offers excellent amplifier matching which is impor-
tant for applications such as multiple gain blocks, low noise
instrumentation amplifiers, quad buffers, and low noise active
filters.
The OP470 conforms to the industry standard 14-lead DIP
pinout. It is pin compatible with the LM148/149, HA4741,
HA5104, and RM4156 quad op amps and can be used to up-
grade systems using these devices.
For higher speed applications, the OP471, with a slew rate of 8
V/ms, is recommended.

The 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
±

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.
