The 16-bit DAC82002 is a highly accurate, low-power, dual-channel digital-to-analog converter (DAC) with an unbuffered voltage output.

The DAC82002 works with 3.3-V and 5-V supplies and offers linearity of 1‑LSB DNL and 2‑LSB INL. The high accuracy combined with a tiny package make the device an excellent choice for applications such as gain and offset calibration, voltage set point generation, and power-supply control. The DAC82002 incorporates a power-on-reset circuit to make sure that the DAC output powers up at zero scale or midscale based on the status of RSTSEL pin, and remains at that scale until a valid code is written to the device. All internal registers are asynchronously reset after the RESET pin is pulled low.

The DAC82002 uses a versatile, three-wire serial peripheral interface (SPI) that operates at clock rates of up to 50 MHz.
