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 180 MHz and very fast slew rate of 50 V/μs produce exceptionally low distortion. Very low input
noise of 1.3 nV/√Hz further ensures maximum signal-to-noise ratio and
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
A shutdown feature also enhances the flexibility of this amplifier.
The OPA1632 is available in an SO-8 package and a thermally-enhanced MSOP-8
