The TLV5618A is a dual 12-bit voltage output DAC with a flexible 3-wire serial interface. The serial interface is compatible with TMS320, SPIE, QSPIE, and Microwire^TM serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits.

The resistor string output voltage of the TLV5618A 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 programmable 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.
