The OP200 is the first monolithic dual operational amplifier to offer OP77 type precision performance. Available in the industry standard 8-pin 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 75µV with a drift below 0.5µV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP-200 exceeds 5,000,000 into a 10k Ohm load; input bias current is under 2nA; CMR is over 120dB and PSRR below 1.8µV/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 nulling. The total current drawn by the dual OP200 is less than one-half that of a single OP07, yet the OP200 offers significant improvements over this industry standard op amp. The voltage noise density of the OP200, 11nV/(root)Hz at 1kHz, is half that of most competitive devices. The OP200 is an ideal choice for applications requiring multiple precision op amps and where low power consumption is critical.
