Overview
The TLV5626CDR is a dual 8-bit voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. It features a flexible 3-wire serial interface, allowing for glueless interface with TMS320, SPI, QSPI, and Microwire serial ports. This DAC is programmed using a 16-bit serial string containing 2 control and 8 data bits. The device includes a programmable internal reference and a rail-to-rail output buffer with a Class AB output stage, enhancing stability and reducing settling time. It operates on a single supply voltage from 2.7 V to 5.5 V and is available in an 8-pin SOIC package, suitable for standard commercial and industrial temperature ranges.
