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 2 55V and 0V to 10 2V 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
