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
comprised 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...
