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.
