Very Low Noise Quad

Operational Amplifier

OP470

FEATURES

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.

Very Low-Noise, 5 nV/÷Hz @ 1 kHz Max

Excellent Input Offset Voltage, 0.4 mV Max

Low Offset Voltage Drift, 2 ꢀV/ꢁC Max

Very High Gain, 1000 V/mV Min

Outstanding CMR, 110 dB Min

Slew Rate, 2 V/ꢀs Typ

Gain-Bandwidth Product, 6 MHz Typ

Industry Standard Quad Pinouts

Available in Die Form

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.

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.
