ADC TRANSFER FUNCTION
The ADS8028 output is in straight binary format for all analog input channels (AIN0 to AIN7) and is in twos
complement format for the temperature sensor conversion result. The transition in output code occurs at every
LSB step. For the ADS8028, LSB step size is V
REF
/4096. The ideal ADS8028 transfer characteristic for straight
binary coding is shown in Figure 32.
