D OR PW PACKAGE (TOP VIEW)
The TLV5627 is a four channel, 8-bit voltage output digital-to-analog converter (DAC) with a flexible 4-wire serial interface. The 4-wire serial interface allows glueless interface to TMS320,
DVDD 1 PD 2
LDAC 3
16 AVDD 15 REFINAB
14 OUTA
SPI, QSPI, and Microwire serial ports. The
DIN 4 13 OUTB
TLV5627 is programmed with a 16-bit serial word
SCLK 5 12 OUTC prised of a DAC address, individual DAC
CS 6
11 OUTD control bits, and an 8-bit DAC value.
FS 7 10 REFINCD
The device has provision for two supplies: one
DGND 8
9 AGND 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 will be controlled via a microprocessor operating on a 3-V supply (also used on pins DVDD and DGND), with the DACs...
