AN-1525 Single Supply Operation of the DAC0800 and
DAC0802
ABSTRACT
This application report develops the positive-only bias voltages needed to successfully operate the
ADC0800 and the DAC0802 with a single supply voltage. The principles here also apply to the DAC0808,
which is a two quadrant multiplying DAC with a single output.
