that features OP77-type performance. Precision performance is
not sacrificed with the OP400 to obtain the space and cost savings
offered by quad amplifiers.
The OP400 features an extremely low input offset voltage of less
than 150 μV with a drift of less than 1.2 μV/°C, guaranteed over
the full military temperature range. Open-loop gain of the OP400
is more than 5 million into a 10 kΩ load, input bias current is
less than 3 nA, common-mode rejection (CMR) is more than
120 dB, and power supply rejection ratio (PSRR) is less than
1.8 μV/V. On-chip Zener zap trimming achieves the low input
offset voltage of the OP400 and eliminates the need for offset + + – OP400 16 OUT D 15 –IN D 14 +IN D 13 V– 12 +IN C 11 –IN C +IN B 5 10 +IN C –IN B 6 9 –IN C OUT B 7 10 OUT C 8 OUT C NC 8 9 NC – + + – NC = NO CONNECT Figure 1. 14-Lead Ceramic Dual In-Line
