DS202F5
Differential input pins into the device.
Fully differential inputs which establish the voltage reference for the on-chip modulator.
Input pin to supply the negative supply voltage for the 20X gain instrumentation amplifier.
May be tied to AGND if AIN+ and AIN- inputs are centered around +2.5 V; or it may be tied
to a negative supply voltage (-2.1 V typical) to allow the amplifier to handle low level signals
more negative than ground.
Square wave output used to provide energy for the charge pump.
Positive analog supply voltage. Nominally +5 V.
Positive digital supply voltage. Nominally +3.0 V or +5 V.
Analog Ground.
Digital Ground.
