SDI is the input pin of the serial input port. Data will be input at a rate determined by SCLK.
A clock signal on this pin determines the input/output rate of the data for the SDI/SDO pins
respectively. This input is a Schmitt trigger to allow for slow rise time signals. The SCLK pin
will recognize clocks only when CS is low.
The logic states of A1-A0 mimic the OL1-OL0 bits in the selected Setup, or the A1-A0 bits in
the Configuration Register, depending on the state of the OLS bit in the Configuration Register.
Logic Output 0 = VA-, and Logic Output 1 = VA+. Alternately, A0 can be used as a guard drive
for the instrumentation amplifier with proper setting of the GB bit in the Configuration Register.
Differential input pins into the device.
Fully differential inputs which establish the voltage reference for the on-chip modulator.
Connections for the instrumentation amplifier’s capacitor.
Positive analog supply voltage.
Positive digital supply voltage (nominally +3.0 V or +5 V).
Negative analog supply voltage.
Digital Ground.
SDO is the serial data output. It will output a high impedance state if CS = 1.
