The OPA1633 is a
fully differential amplifier (FDA) designed to drive high-performance audio
analog-to-digital converters (ADCs) or as a predriver for class-D amplifiers.
The OPA1633 delivers excellent audio quality, very low
noise, a large output voltage swing, and a high current drive. The OPA1633 has an excellent gain bandwidth of 200 MHz and a very fast
slew rate of 80 V/µs that helps produce exceptionally low distortion. A very low
input voltage noise of 1.1 nV/√Hz further provides 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 OPA1633 provides
excellent performance when used to drive high-performance audio ADCs such as the
PCM1804. A shutdown feature is included to save power when the device is
not in use.
The OPA1633 is
characterized to operate from −40°C to +85°C and available in an SO-8 package and a
thermally enhanced, HVSSOP PowerPAD™ integrated circuit
package.
