OPA1632 全差动 I/O 音频放大器

The OPA1632 is a fully-differential amplifier designed for driving high-performance audio analog-to-digital converters (ADCs). It provides the highest audio quality, with very low noise and output drive characteristics optimized for this application. The OPA1632’s excellent gain bandwidth of 180MHz and very fast slew rate of 50V/µs produce exceptionally low distortion. Very low input noise of 1.3nV/√Hz further ensures 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
