 open-in-new Find other Precision DACs (<=10MSPS)

Description

The DAC8820, a 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 VREF determines the full-scale output current. An internal feedback resistor (RFB) provides temperature tracking for the full-scale output when combined with an external, current-to-voltage (I/V) precision amplifier.

A parallel interface offers high-speed communications. The DAC8820 is packaged in a space-saving SSOP-28 package and has an industry-standard pinout.
