Overview
The TLV5618AMDREPG4 is a 12-bit digital-to-analog converter (DAC) produced by Texas Instruments. This device features a dual 12-bit voltage output DAC with a flexible 3-wire serial interface compatible with TMS320, SPI, QSPI, and Microwire serial ports. It is designed for single supply operation from 2.7 V to 5.5 V and is available in an 8-pin SOIC package. The TLV5618A series, including the TLV5618AMDREPG4, is characterized by its programmable settling time, allowing designers to optimize between speed and power dissipation. The device is implemented using a CMOS process and features a Class-AB output stage to improve stability and reduce settling time.
