See the Channel Configuration Options section for a detailed description of unipolar mode, pseudo bipolar mode, and the channel pin assignment options.

IN+ and IN− represent the analog inputs connected to the positive and negative inputs of the AD4695/AD4696 ADC core via the internal multiplexer (see the

Multiplexer section and Channel Configuration Options section).

The analog input leakage current specification refers to the input current of the analog input pins during periods when the ADC is not performing conversions and the

analog input voltage is already settled.

Offset error and gain error specifications are taken with the offset and gain correction registers set to the default values, which correspond to no offset or gain

correction. See the Offset and Gain Correction section for more information.

%FS is the percentage of the ADC full-scale (see the Transfer Function section for a definition of full scale).

REXT and CEXT refer to the resistor and capacitor, respectively, that make up the recommended external RC filters at the analog inputs (see the External RC Filter section).

For the power supply current and power dissipation specifications where analog input high-Z mode is enabled, analog input high-Z mode is set to be enabled for all

channels. The power consumption scales with the percentage of conversions performed with analog input high-Z mode enabled.
