Specification is not production tested but is supported by characterization data at initial product release.
Full-scale error applies to both positive and negative full scale and applies at the factory calibration conditions (V
The AD7787 can tolerate absolute analog input voltages down to GND − 200 mV but the leakage current will increase.
FS[2:0] are the three bits used in the filter register to select the output word rate.
Digital inputs equal to V
The current consumption can be further reduced by using the ADC in one of the low power modes (see Table 14).
