The serial interface is compatible with TMS320, SPI, QSPI, and Microwire serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits. The resistor string output voltage is buffered by an x2 gain rail-to-rail output buffer. The buffer features a Class-AB output stage to improve stability and reduce settling time. The programmable settling time of the DAC allows the designer to optimize speed versus power dissipation. NC OUTA NC AGND NC 3 2 1 20 19 NC 4 18 NC SCLK 5 17 OUTB NC 6 16 NC CS 7 15 REF ...
