3 Description

The OPA1633 is a fully differential amplifier (FDA) designed to drive high-performance audio analog-to-digital converters (ADCs) or as a predriver for class-D amplifiers.

The OPA1633 delivers excellent audio quality, very low noise, a large output voltage swing, and a high current drive. The OPA1633 has an excellent gain bandwidth of 200 MHz and a very fast slew rate of 80 V/μs that helps produce exceptionally low distortion. A very low input voltage noise of 1.1 nV/√Hz further provides maximum signal-to-noise ratio and dynamic range.

The flexibility of the fully differential architecture allows for easy implementation of a single-ended to fully differential output conversion. Differential output reduces even-order harmonics and minimizes common-mode noise interference. The OPA1633 provides excellent performance when used to drive high-performance audio ADCs such as the PCM1804. A shutdown feature is included to save power when the device is not in use.

The OPA1633 is characterized to operate from −40°C to +85°C and available in an SO-8 package and a thermally enhanced, HVSSOP PowerPAD™ integrated circuit package.
