description

The TLV5618A is a dual 12-bit voltage output DAC

with a flexible 3-wire serial interface. The serial

interface is compatible with TMS320, 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 an

x2 gain rail-to-rail output buffer. The buffer

features a Class-AB output stage to improve

stability and reduce settling time. The program-

mable settling time of the DAC allows the designer

to optimize speed versus power dissipation.

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 in standard commercial and industrial temperature ranges.

The TLV5618AC is characterized for operation from 0

°C to 70°C. The TLV5618AI is characterized for operation

from – 40

°C to 85°C. The TLV5618AQ is characterized for operation from –40°C to 125°C. The TLV5618AM

is characterized for operation from – 55

°C to 125°C.
