3 Description

The DAC8811 multiplying digital-to-analog converter (DAC) is designed to operate from a single 2.7-V to 5.5-V supply.

The applied external reference input voltage V_REF determines the full-scale output current. An internal feedback resistor (R_FB) provides temperature tracking for the full-scale output when combined with an external I-to-V precision amplifier.

A serial data interface offers high-speed, three-wire microcontroller-compatible inputs using data-in (SDI), clock (CLK), and chip-select (CS).

On power-up, the DAC register is filled with zeroes, and the DAC output is at zero scale.

The DAC8811 is packaged in space-saving 8-lead VSON and VSSOP packages.
