Precision 16-Bit, Bipolar Output Voltage Source with +12 V to ±5 V Supply

Circuit provides a precision 16-bit, low drift bipolar voltage output of ±2.5 V and operates on a single +10 V to +15 V supply. The unipolar voltage outputs of the AD5668 octal denseDAC are amplified and level shifted by the AD8638 auto-zero Op-Amps
