描述 Description

The 16-bit DAC82001 is a highly accurate, low-power, single-channel digital-to-analog converter (DAC) with an unbuffered voltage output.

The DAC82001 works with 3.3-V and 5-V supplies and offers linearity of 1‑SB 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 DAC82001 incorporates a power-on-reset (POR) circuit. The POR circuit makes 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 DAC82001 uses a versatile, three-wire serial peripheral interface (SPI) that operates at clock rates of up to 50 MHz.
