3 Description

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

‑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 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.
