OPA1632D General Description

The OPA1632 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 OPA1632 delivers excellent audio quality, very low noise, large output voltage swing, and high current drive. The OPA1632 has an excellent gain bandwidth of 180 MHz, and a very fast slew rate of 72 V/µs that helps to produce exceptionally low distortion. A very low input voltage noise of 1.25 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 OPA1632 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 OPA1632 is characterized to operate from –40°C to +85°C and is available in an SO-8 package and a thermally-enhanced HVSSOP-8 PowerPAD™ integrated circuit package.

It was not until the end. They threw it in the mailbox. Which is unexpected. corresponds to the description. thank you to the seller. I recommend. Tearing current from battery to two amps.

With my screwdriver made friends

K**n 12/09/2020

It came perfectly packed. The only negative, there is no marking where and which color, it is better to put 5 bags with colors different.
