OP37GSZ-REEL7

The OP37GSZ-REEL7 from Analog Devices is a high-performance operational amplifier designed for applications requiring low noise, precision, and high speed. Optimized for circuits with gains greater than five, it boasts a typical slew rate of 17 V/µs and a gain bandwidth product of 63 MHz.

Key features include exceptionally low noise, with a typical value of 80 nV p-p from 0.1 Hz to 10 Hz, and a low 1/f noise corner frequency of 2.7 Hz. The amplifier also exhibits low input offset voltage (10 µV typical) and low temperature drift (0.2 µV/°C typical), making it suitable for precision instrumentation.

With a high open-loop gain of 1.8 million and excellent CMRR (126 dB typical), the OP37GSZ-REEL7 can accurately amplify low-level signals. Its output stage provides good load driving capability, with a guaranteed swing of 10 V into 600 Ω and low output distortion, making it an excellent choice for professional audio applications. The device is supplied in an 8-Lead SO package.

This operational amplifier is well-suited for diverse applications such as microphone, tapehead, and RIAA phono preamplifiers, as well as high-speed signal conditioning for data acquisition systems and wide-bandwidth instrumentation.
