DESCRIPTION
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/
μ
s 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
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.
