GENERAL DESCRIPTION
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 75 μV with a drift below 0.5 μV/∞C, guaranteed over the full military temperature range. Open-loop gain of the OP200 exceeds 5,000,000 into a 10 kΩ load; input bias current is under 2 nA; CMR is over 120 dB and PSRR below 1.8 μV/V. On-chip zenerzap trimming is used to achieve the extremely low input offset voltage of the OP200 and eliminates the need for offset pulling.
Power consumption of the OP200 is very low, with each amplifier drawing less than 725 μA of supply current. 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, 11 nV/ Hz at 1 kHz, is half that of most competitive devices.
The OP200 is pin compatible with the OP221, LM158, MC1458/1558, and LT1013.
