The OPA1632 is a fully-differential amplifier (FDA) designed to drive high-performance audio analog-to-digital converters (ADCs) or as a pre-driver for Class-D amplifiers. It delivers superior audio quality, very low noise, large output voltage swing and high current drive. The OPA1632 has an excellent gain bandwidth of 180 MHz and very fast slew rate of 72 V/µs which helps to produce exceptionally low distortion. A very low input voltage noise of 1.25 nV/√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. The OPA1632 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 being used.
The OPA1632 is characterized for operation from –40°C to +85°C and is available in an SO-8 package and a thermally-enhanced MSOP-8 PowerPAD™ package.
