TLV5614IYZ,PDF(12-Bit, Quad Ch

The TLV5614IYZ is a quadruple, 12-bit, voltage output digital-to-analog converter (DAC) with a flexible 4-wire serial interface. The serial interface allows glueless interface to TMS320, SPI, QSPI, and Microwire serial ports. The TLV5614IYZ is programmed with a 16-bit serial word comprised of a DAC address, individual DAC control bits, and a 12-bit DAC value. The device has provision for two supplies: one digital supply for the serial interface (via pins DV_DD and DGND), and one for the DACs, reference buffers, and output buffers (via pins AV_DD and AGND). Each supply is independent of the other, and can be any value between 2.7V and 5.5V. The dual supplies allow a typical application where the DAC is controlled via a microprocessor operating on a 3V supply (also used on pins DV_DD and DGND) with the DACs operating on a 5V supply.
