A true 16 b self-calibrating BiCMOS DAC

An instrument-grade DAC (digital-to-analog converter) that produces true 16-b performance after a brief calibration period and retains accuracy over a usable temperature range is described. Typical results for DNL (differential nonlinearity) and end-point INL (integral nonlinearity) for the 10-V uni...

Description
Summary:An instrument-grade DAC (digital-to-analog converter) that produces true 16-b performance after a brief calibration period and retains accuracy over a usable temperature range is described. Typical results for DNL (differential nonlinearity) and end-point INL (integral nonlinearity) for the 10-V unipolar range at 25 degrees C and for the calibrated top 6 b only are shown. The chip occupies 80 kmils/sup 2/ in a BiCMOS process, and dissipates 500 mW from +or-15-V/+5-V supplies.< >
