DESCRIPTION  
SUPERIOR SOUND QUALITY  
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/µs produce exceptionally low distortion. Very low  
input noise of 1.3nV/Hz further ensures maximum  
signal-to-noise ratio and dynamic range.

ULTRA LOW DISTORTION: 0.000022%  
LOW NOISE: 1.3nV/Hz  
HIGH SPEED:  
− Slew Rate: 50V/µs  
− Gain Bandwidth: 180MHz

FULLY DIFFERENTIAL ARCHITECTURE:  
− Balanced Input and Output Converts  
Single-Ended Input to Balanced  
Differential Output  
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.
