Overview
The TLV5638CDG4 is a dual 12-bit voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. It features a flexible 3-wire serial interface that allows for glueless connection to TMS320, SPI™, QSPI™, and Microwire™ serial ports. This device is programmed using a 16-bit serial string containing 4 control and 12 data bits. The TLV5638CDG4 is designed for single supply operation from 2.7 V to 5.5 V and is available in an 8-pin SOIC package, as well as JG and FK packages for military temperature ranges.
