The TLV5618A is a dual 12-bit voltage output DACwith a flexible 3-wire serial interface. The serialinterface is compatible with TMS320, SPI,QSPI, and Microwire serial ports. It isprogrammed with a 16-bit serial string containing4 control and 12 data bits.
The resistor string output voltage is buffered by anx2 gain rail-to-rail output buffer. The bufferfeatures a Class-AB output stage to improvestability and reduce settling time. The programmablesettling time of the DAC allows the designerto 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. Itis 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 operationfrom –40°C to 85°C. The TLV5618AQ is characterized for operation from –40°C to 125°C. The TLV5618AMis characterized for operation from –55°C to 125°C.
