DAC43902RTERQ1 TI DAC | 16-WQFN (3x3) | 10-bit, 2-Ch, I2C

Product Overview

The DAC43902RTERQ1 is a 10-bit, dual-channel, voltage-output digital-to-analog converter (DAC) from Texas Instruments, designed for automotive applications. It operates from a single 2.7V to 5.5V supply and features an I2C interface with up to 3.4 MHz. The device is offered in a compact 16-pin WQFN (3x3 mm) package, making it suitable for space-constrained designs. It includes a power-on reset to zero-scale and a low-power mode, ensuring reliable operation in automotive environments.
