ADVANCE INFORMATION for pre-production products; subject to change without notice.
The differential voltages at the analog inputs are captured by the rising edge of CLK± in dual-channel mode or by the rising and falling edges of CLK± in single-channel mode. 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 INA– or INB– is higher than the voltage on INA+ or INB+, respectively, then the digital output is a negative 2's complement value. If the voltage on INA+ or INB+ is higher than the voltage on INA– or INB–, respectively, 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.
