The OPA1632 is a fully-differential amplifier designedfor driving high-performance audio analog-to-digitalconverters (ADCs). It provides the highest audio quality,with very low noise and output drive characteristicsoptimized for this application. The OPA1632’s excellentgain bandwidth of 180MHz and very fast slew rate of50V/μs produce exceptionally low distortion. Very lowinput noise of 1.3nV/√Hz further ensures maximumsignal-to-noise ratio and dynamic range.The flexibility of the fully differential architecture allowsfor easy implementation of a single-ended tofully-differential output conversion. Differential outputreduces even-order harmonics and minimizescommon-mode noise interference. The OPA1632provides excellent performance when used to drivehigh-performance audio ADCs such as the PCM1804.A shutdown feature also enhances the flexibility of thisamplifier.The OPA1632 is available in an SO-8 package and athermally-enhanced MSOP-8 PowerPAD package.
