Overview
The TLV5638IDR 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 DAC is designed for single supply operation from 2.7 V to 5.5 V and is available in an 8-pin SOIC package, making it suitable for applications where board space is limited. The device is implemented using a CMOS process and includes a programmable precision voltage reference, which simplifies overall system design.
