Overview
The TLV5616 is a 12-bit voltage output digital-to-analog converter (DAC) designed by Texas Instruments. It features a flexible 4-wire serial interface compatible with TMS320, SPI, QSPI, and Microwire serial ports. This DAC is programmed using a 16-bit serial string containing 4 control bits and 12 data bits. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and is available in an 8-terminal SOIC package. The device is characterized for operation in two temperature ranges: 0°C to 70°C (TLV5616C) and −40°C to 85°C (TLV5616I).
