DAC7822IRTAT TI DAC | 40-WQFN (6x6) | 12-Bit, Dual, Rail-to-Rail

Product Overview

The DAC7822IRTAT is a dual, 12-bit, voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates from a single 2.7V to 5.5V supply and features rail-to-rail output swing. The device includes a power-on reset circuit that ensures the DAC outputs are at zero scale when power is applied. The DAC7822 uses a 3-wire serial interface (SPI) that operates at clock rates up to 50 MHz, making it suitable for high-speed applications. It is available in a compact 40-pin WQFN package (6x6 mm) for space-constrained designs.
