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 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.
The TLV5618AM is characterized for operation from − 55°C to 125°C.
