The TLV5638CD is a dual 12-bit voltage output Digital-to-analog Converter (DAC) with a flexible 3-wire serial interface. The serial interface allows glueless interface to TMS320 and 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 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 vs power dissipation. With its on-chip programmable precision voltage reference, the TLV5638 simplifies overall system design. Because of its ability to source up to 1mA, the reference can also be used as a system reference. Implemented with a CMOS process, the device is designed for single supply operation from 2.7 to 5.5V.
