7.2.1 Design Requirements

Design a single supply data acquisition system capable of digitizing a pressure sensor output. In addition to digitizing the pressure sensor output, use the DAC121S101-SEP to correct gain errors in the pressure sensor output by adjusting the bias voltage to the bridge pressure sensor. Table 7-1 lists the design parameters for DAC121S101-SEP.
