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 1 mA, 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 V to 5.5 V. It is available in

an 8-pin SOIC package to reduce board space in standard commercial and industrial temperature ranges.
