TLV5604 is a 10-bit 3 µS quad digital-to-analog converter (DAC) with a flexible 4-wire serial interface from TI. It has a flexible 4-wire serial interface that allows glueless interface to TMS320, SPI, QSPI, and Microwire serial ports. The TLV5604 is programmed with a 16-bit serial word comprised of a DAC address, individual DAC control bits, and a 10-bit DAC value. The device has provision for two supplies: one digital supply for the serial interface (via pins DVDD and DGND), and one for the DACs, reference buffers and output buffers (via pins AVDD and AGND). Each supply is independent of the other and can be used independently.
