OP37AZ Description

Short technical summary and product information.

The OP37AZ from Analog Devices is a precision, high-speed operational amplifier designed for applications requiring gains greater than five. It builds upon the performance of the OP27, enhancing slew rate to 17 V/µs and gain-bandwidth product to 63 MHz.

This amplifier provides exceptionally low noise characteristics, with a spectral density of 3 nV/√Hz at 1 kHz and 80 nVp-p from 0.1 Hz to 10 Hz. Its low input offset voltage (10 µV typical) and drift (0.2 µV/°C typical) make it suitable for precision instrumentation. The OP37AZ also features a high open-loop gain of 1.8 million and excellent CMRR of 126 dB.

Designed for high-volume production, the OP37AZ utilizes on-chip zener-zap trimming for stable offset correction. It is available in 8-lead hermetic DIP, epoxy mini-DIP, and 8-lead SO packages, supporting through-hole mounting.

Applications include microphone, tapehead, and RIAA phono preamplifiers, as well as high-speed signal conditioning circuits where accurate amplification of low-level signals is critical.
