Description

This multiplying DAC (MDAC) circuit creates a unipolar voltage output from 0 V to 2.5 V. This design does not require dual supplies to realize a unipolar, positive output voltage as with typical MDAC circuits. This design removes the need for a negative rail by using the MDAC in “reverse” to form a binary weighted voltage divider.

Features
  •  12-bit, 0-2.5 V output
  •  Multiplying DAC with single supply
  •  <0.1 %FSR total unadjusted error
