Differential analog input pins. The differential full-scale input
signal level is two times the reference voltage with each input
pin signal centered on a common mode voltage, V
These pins should each be bypassed to AGND with a low
ESL (equivalent series inductance) 0.1 µF capacitor placed
very close to the pin to minimize stray inductance. A 0.1 µF
capacitor should be placed between V
to the pins as possible, and a 10 µF capacitor should be
placed in parallel.

This pin can be used as either the +1.0V internal reference
voltage output (internal reference operation) or as the
external reference voltage input (external reference
operation).
To use the internal reference, V
AGND with a 0.1 µF, low equivalent series inductance (ESL)
capacitor. In this mode, V
internal 1.0V reference.
To use an external reference, overdrive this pin with a low
noise external reference voltage. The input impedance
looking into this pin is 9kΩ. Therefore, to overdrive this pin,
the output impedance of the external reference source
should be << 9kΩ.
This pin should not be used to source or sink current.
The full scale differential input voltage range is 2 * V
