DAC7811IDGS TI DAC | 10-VSSOP | 12-Bit, Serial Input, Single Channel

Product Overview

The DAC7811IDGS is a 12-bit, single-channel, serial-input digital-to-analog converter (DAC) from Texas Instruments. It operates from a single 2.7V to 5.5V supply and features a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP interfaces. The device is offered in a compact 10-pin VSSOP package, making it ideal for space-constrained applications. The DAC7811IDGS includes a power-on reset circuit that ensures the DAC output powers up at 0V and remains there until a valid write to the device takes place. It also has a power-down feature that reduces current consumption to typically 0.5 µA at 5V.
