Overview
The TLV5614IDR from Texas Instruments is a quadruple 12-bit voltage output digital-to-analog converter (DAC) designed for a wide range of applications. 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 word that includes the DAC address, individual DAC control bits, and a 12-bit DAC value. The device is notable for its low power consumption, programmable settling time, and dual supply capability, making it suitable for various industrial and communication applications.
