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...
