Overview
The TLV5618A, produced by Texas Instruments, is a dual 12-bit voltage output Digital-to-Analog Converter (DAC) designed for high precision and flexibility. It features a 3-wire serial interface compatible with TMS320, SPI, QSPI, and Microwire serial ports. The device is programmed using a 16-bit serial string containing 4 control and 12 data bits. The TLV5618A is implemented with a CMOS process, allowing single supply operation from 2.7 V to 5.5 V, and is available in an 8-pin SOIC package. It is characterized for operation over various temperature ranges, including commercial, industrial, and extended temperature options.
