Gain Selection

The Gain control pin G is a tertiary control pin

where state 0 is GND, state 1 is VREF level

and state 2 is VDD.

The sample rate ratio is twice the clock to cor-

ner ratio (double sampling).

Pin Configuration

Note that the large pads on the solder side of

the VDFN package is tied internally to VDD.
