Overview
The TLV5618AIDR is a dual 12-bit voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. It features a flexible 3-wire serial interface compatible with TMS320, SPI, QSPI, and Microwire serial ports. This device is designed for single supply operation from 2.7 V to 5.5 V and is available in an 8-pin SOIC package. The TLV5618AIDR is characterized by its programmable settling time, allowing designers to optimize between speed and power dissipation. It is also a direct replacement for the TLC5618A (C and I suffixes) and is available in various temperature ranges, including Q-Temp automotive and HighRel automotive applications.
