Details

• 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 OPA1632s excellent gain bandwidth of 180 MHz and very fast slew rate of 50 V/s produce exceptionally low distortion. Very low input noise of 1.3 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 also enhances the flexibility of this amplifier
• The OPA1632 is available in an SO-8 package and a thermally-enhanced MSOP-8 PowerPAD package
