ADOP37FQ

Overview

The ADOP37FQ is a low noise, precision, high-speed operational amplifier manufactured by Analog Devices Inc. It provides performance similar to the OP27 but is optimized for circuits with gains greater than five. Key electrical characteristics include a slew rate of 17 V/µs and a gain-bandwidth product of 63 MHz. The device features low input offset voltage of 10 µV, low drift of 0.2 µV/°C, and excellent common-mode rejection ratio (CMRR) of 126 dB at 11 V common-mode voltage. Noise specifications are 80 nV p-p from 0.1 Hz to 10 Hz and 3 nV/√Hz at 1 kHz. Open-loop gain is 1.8 million.

Feature Summary

• Optimized for high-gain applications exceeding unity gain
• Low noise performance suitable for precision signal conditioning
• High slew rate and wide bandwidth for fast signal response

Applications

• Precision instrumentation amplifiers
• High-speed data acquisition systems
• Active filters requiring low distortion

Procurement Notes

Verify the specific suffix 'FQ' against official Analog Devices documentation to confirm package type, temperature range, and tape/reel specifications. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this component when circuit designs require gains greater than five and demand high speed combined with low noise. It serves as a direct replacement for OP27, OP-07, and SE5534 in applicable configurations where higher slew rate and bandwidth are necessary.

Part Context

The ADOP37FQ belongs to the OP37 family of operational amplifiers. This series is designed to offer enhanced performance over the OP27, specifically targeting applications where high gain stability and speed are critical. It is part of Analog Devices' portfolio of precision analog components.

Replacement Considerations

Officially documented replacements include OP27, OP-07, and SE5534 for circuits with gains greater than five. Verify pinout and electrical parameter compatibility before substitution.
