GENERAL DESCRIPTION
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.

BIAS
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.
