The equivalent LSB size at the input of the PGA chain is:
Notice that the input voltage VIN,ADC of the ADC must satisfy the condition:
to remain within the ADC input range.
7.7.9 Power Saving Modes
During low-speed operation, the bias current in the PGAs and ADC can be programmed to save power using the
control words IbAmpPga[1:0] and IbAmpAdc[1:0] (see Table 21). If the system is idle, the PGAs and ADC can even be
disabled, thus, reducing power consumption to its minimum. This can considerably improve battery lifetime.
