GENERAL DESCRIPTION
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 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
Zener zap 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.
The OP200 is an ideal choice for applications requiring multiple
precision op amps and where low power consumption is critical.
For a quad precision op amp, see the OP400.
