Clamp reference voltage input.

Clamps so that the reference voltage

and the clamp interval ADIN input signal

are equal.

The reference voltage is more than 0.5V.

Amplifier input pin.

Biased internally

at 1.9V (when AVDD = 5V) or

at 1.8V (when AVDD = 4.75V).

When in standby as well.

When SEL is at Low level, VIN1 is

selected for input;

When SEL is at High level, VIN2 is

selected for input.

5V or 4.75V
