Overview
The TLV5618ACD, produced by Texas Instruments, is a dual 12-bit voltage output Digital-to-Analog Converter (DAC) designed for a wide range of applications. It features a flexible 3-wire serial interface compatible with 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 TLV5618ACD is implemented with a CMOS process, allowing for single supply operation from 2.7 V to 5.5 V, and is available in an 8-pin SOIC package.
