PRODUCTION DATA
The differential voltages at the analog inputs are captured by the rising edge of CLK±. After capturing the input signal the ADC converts the analog voltage to a digital value by comparing the voltage to the internal reference voltage. If the voltage on the negative input (that is, INA–) is higher than the voltage on the positive input (that is, INA+) then the digital output is a negative 2's complement value. If the voltage on the positive input is higher than the voltage on the negative input then the digital output is a positive 2's complement value. Equation 1 can calculate the differential voltage at the input pins from the digital output.
