1 Introduction

The OPA1637 is a high-performance, low-noise, low total harmonic distortion (THD), fully differential amplifier that can easily filter and drive fully differential audio signal chains from Texas Instruments. For a full list of electrical characteristics, see the OPA1637 High-Performance, High-Voltage, Low -Noise, Burr-Brown™ Fully Differential Amplifier data sheet.

The OPA1637EVM is configured by default in a second-order, low-pass, Butterworth filter configuration with a gain of 5-V/V and a corner frequency of 30-kHz. Input and output connections are accessible using SMA connectors and XLR audio connectors.
