GENERAL DESCRIPTION

The OP200 is the first monolithic dual operational amplifier

to offer OP77 type precision performance. Available in the

industry standard 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; CMRR is over 120 dB; and PSRR is 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 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/MC1558, 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.
