The OP200 is the first monolithic dual operational amplifier to offer OP77 type precision performance. Available in the industrystandard 8-lead pinout, the OP200 combines precision performance with the space and cost savings offered by a dual amplifier. The OP200 features an extremely low input offset voltage of less than 75 V with a drift below 0.5 V/C, guaranteed over the full military temperature range. Open-loop gain of the OP200 exceeds 5,000,000 into a 10 k load; input bias current is under 2 nA; CMR is over 120 dB and PSRR below 1.8 V/V. On-chip Zener zap trimming is used to achieve the extremely low input offset voltage of the OP200 and eliminates the need for offset pulling.
