Overview
The TLV5626IDRG4 is a dual 8-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device operates on a single supply voltage ranging from 2.7 V to 5.5 V and is designed for low-power applications. It features a flexible 3-wire serial interface compatible with TMS320 and SPI, QSPI, and Microwire serial ports. The TLV5626IDRG4 includes an on-chip programmable precision voltage reference and a Class AB output stage to enhance stability and reduce settling time. It is available in an 8-pin SOIC package, suitable for both commercial and industrial temperature ranges.
