description

The TLV5614 is a quadruple 12-bit voltage output

digital-to-analog converter (DAC) with a flexible

four-wire serial interface. The four-wire serial

interface allows glueless interface to TMS320?

DSP family, SPI?, QSPI?, and Microwire? serial

ports. The TLV5614 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

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 any value between 2.7 V and 5.5 V. The dual supplies allow a typical application where the DAC is

controlled via a microprocessor operating on a 3-V supply (also used on pins DVDD and DGND), with the DACs

operating on a 5-V supply. The digital and analog supplies can be tied together.
