Function
Analog Input to the inverting input amplifier on Channel 1’s positive input.
Feedback Connection from the output of the inverting amplifier on Channel 1’s positive input. When the input amplifiers are
bypassed, this pin allows direct access to the positive input of Channel 1’s sigma-delta modulator.
Analog Input to the inverting input amplifier on Channel 1’s negative input.
Feedback connection from the output of the inverting amplifier on Channel 1’s negative input. When the input amplifiers are
bypassed, this pin allows direct access to the negative input of Channel 1’s sigma-delta modulator.
Buffered Reference Output, which has a nominal value of 1.2 V.
A bypass capacitor to AGND2 of 0.1 µF is required for the on-chip reference. The capacitor should be fixed to this pin.
Analog Power Supply Connection.
Analog Ground/Substrate Connection2.
Digital Ground/Substrate Connection.
Digital Power Supply Connection.
Active Low Reset Signal. This input resets the entire chip, resetting the control registers and clearing the digital circuitry.
