Dual Low Offset, Low Power

Operational Amplifier

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

mV with a drift below 0.5 mV/∞C, guaranteed over the full

military temperature range. Open-loop gain of the OP200 exceeds

5,000,000 into a 10 k

W load; input bias current is under 2 nA;

CMR is over 120 dB and PSRR below 1.8

mV/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

mA 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.
