DACA Force-Sense Output. Analog input to mux.
Analog Ground
Analog Supply Voltage. Also ADC reference voltage during AV
10µF and 0.1µF capacitors in parallel as close to the pin as possible.
Amplifier 2 Noninverting Input
Amplifier 2 Inverting Input. Analog input to mux.
Amplifier 2 Output. Analog input to mux.
Analog Input 2. Analog input to mux. Inputs have internal programmable current source for external
temperature measurement.
Analog Input 1. Analog input to mux. Inputs have internal programmable current source for external
temperature measurement.
Reference Input/Output. Output of the reference buffer amplifier or external reference input. Disabled at
power-up to allow external reference. Reference voltage for ADC and DAC.
Linear Voltage-Regulator Output. Charge-pump-doubler input voltage. Bypass REG with a 10µF capacitor
to DGND for charge-pump regulation.
