Product Summary

The OP400AY/883 is a first monolithic quad operational amplifier that features OP77 type performance. Precision performance no longer has to be sacrificed to obtain the space and cost savings offered by quad amplifiers. The OP400AY/883 features an extremely low input offset voltage of less than 150 mV with a drift of under 1.2 μV/℃, guaranteed over the full military temperature range. Open-loop gain of the device is over 5,000,000 into a 10 kW load, input bias current is under 3 nA, CMR is above 120 dB, and PSRR is below 1.8 mV/V. On-chip zener-zap trimming is used to achieve the low input offset voltage of it and eliminates the need for offset nulling. The OP400AY/883 conforms to the industry-standard quad pinout which does not have null terminals.
