OP200AZ

The Analog Devices Inc. OP200AZ is a monolithic dual operational amplifier designed to provide OP77 type precision performance in an industry-standard 8-lead pinout. It combines high precision with the advantages of a dual amplifier, offering significant space and cost savings.

Key electrical characteristics include 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. The open-loop gain exceeds 5,000,000 into a 10 kΩ load, and it features a low input bias current under 2 nA. The device boasts a high CMRR of over 120 dB and PSRR below 1.8 µV/V. On-chip Zener zap trimming ensures the low input offset voltage without the need for offset pulling.

With a low power consumption, each amplifier draws less than 725 µA of supply current. The total current drawn by the dual OP200AZ is less than half that of a single OP07, while offering superior performance. The voltage noise density is 11 nV/√Hz at 1 kHz, which is half that of many competitive devices. The OP200AZ is stable with large capacitive loads up to 10 nF typical.

This operational amplifier is an ideal choice for applications requiring multiple precision op amps where low power consumption is critical. For applications needing a quad precision op amp, the OP400 is available.
