TLV5621ED TI DAC | 14-SOIC | 8-Bit, 4-Ch, 1LSB INL, 1.8V-3.6V

Product Overview

The TLV5621ED from Texas Instruments is a low-power, quad-channel, 8-bit digital-to-analog converter (DAC) with a serial interface. It operates from a single supply voltage ranging from 1.8V to 3.6V, making it ideal for battery-powered and portable applications. The device features a 4-wire SPI-compatible interface (CS, SCLK, DIN, and DOUT) and includes an internal reference voltage. Each DAC output is buffered and can drive capacitive loads up to 100 pF. The TLV5621ED is offered in a 14-pin SOIC package and is specified over the industrial temperature range of -40°C to +85°C.
