DAC0890

Dual 8-bit mP-Compatible Digital-to-Analog Converter

General Description

The DAC0890 is a complete dual 8-bit voltage output digital-

to-analog converter that can operate on a single 5V supply

It includes on-chip output amplifiers precision bandgap volt-

age reference and full microprocessor interface

Each DAC0890 output amplifier has two externally select-

able output ranges 0V to 255V and 0V to 102V The ampli-

fiers are internally trimmed for offset and full-scale accuracy

and therefore require no external user trims

The DAC0890 is supplied in 20-pin ceramic DIP package
