TIPD159, Voltage-Mode Multiplying DAC Reference Design

TIPD159, Voltage-Mode Multiplying DAC Reference Design. This multiplying DAC (MDAC) circuit creates a unipolar voltage output from 0V to 2.5V. 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
