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 Microwireserial 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.
