DAC7642VFT TI DAC | 32-LQFP (7x7) | 16-Bit, 4-Ch, Serial

Product Overview

The DAC7642VFT is a 16-bit, 4-channel, serial-input, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single +5V supply and features a low-power consumption of typically 2.5 mW per channel. The device includes an internal reference (2.5V) and a power-on reset circuit that ensures the DAC outputs are at zero scale when power is applied. The serial interface is compatible with SPI, QSPI, Microwire, and DSP interfaces, making it easy to integrate into various systems. The DAC7642VFT is available in a compact 32-lead LQFP package (7x7 mm) for space-constrained applications.
