3 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?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 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.
