6.3.1 DAC Section

The DAC121S101-SEP is fabricated on a CMOS process with an architecture that consists of switches and a resistor string that are followed by an output buffer. The power supply serves as the reference voltage. The input coding is straight binary with an ideal output voltage of Equation 1:

Equation 1. V O U T = V A × ( D 4096 )

where

  • D is the decimal equivalent of the binary code that is loaded into the DAC register and can take on any value between 0 and 4095.
