DESCRIPTION

The TLV5637 is a dual 10-bit voltage output 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 2

control and 10 data bits.

The resistor string output voltage is buffered by a 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. With its on-chip

programmable precision voltage reference, the

TLV5637 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 2.7V to

5.5V. It is available in an 8-pin SOIC package to

reduce board space in standard commercial and

industrial temperature ranges.
