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.
