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.
