Overview
The TLV5614CDR is a quadruple 12-bit voltage output digital-to-analog converter (DAC) produced by Texas Instruments. It features a flexible 4-wire serial interface, allowing for glueless connection to various serial ports such as TMS320, SPI, QSPI, and Microwire. The device is programmed using a 16-bit serial word that includes a DAC address, individual DAC control bits, and a 12-bit DAC value. It operates with two independent supplies: one for the digital interface and another for the DACs, reference buffers, and output buffers, each ranging from 2.7 V to 5.5 V. This dual supply capability makes it versatile for applications where the DAC and the controlling microprocessor may operate at different voltage levels.
