TLV5637

SLAS224C – JUNE 1999 – REVISED JUNE 2007

2.7V TO 5.5V LOW-POWER DUAL 10-BIT DIGITAL-TO-ANALOG CONVERTER WITH

INTERNAL REFERENCE AND POWER DOWN

• Dual 10-Bit Voltage Output DAC

The TLV5637 is a dual 10-bit voltage output DAC

with a flexible 3-wire serial interface. The serial

• Programmable Internal Reference

interface allows glueless interface to TMS320 and

• Programmable Settling Time:

SPI™, QSPI™, and Microwire™ serial ports. It is

–

0.8µs in Fast Mode

programmed with a 16-bit serial string containing 2

–

2.8µs in Slow Mode

control and 10 data bits.

• Compatible With TMS320 and SPI™ Serial

The resistor string output voltage is buffered by a x2

Ports

gain rail-to-rail output buffer. The buffer features a

Class AB output stage to improve stability and

the

• Digital Servo Control Loops

TLV5637 simplifies overall system design.

• Digital Offset and Gain Adjustment

Because of its ability to source up to 1mA, the

• Industrial Process Control

reference can also be used as a system reference.

• Machine and Motion Control Devices

Implemented with a CMOS process, the device is

designed for single supply operation from 2.7V to

• Mass Storage Devices

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

reduce board space in standard commercial and

industrial temperature ranges.
