DESCRIPTION

Leave open for normal use.

Digital Power Supply +5V or +3.3V.

Leave open for normal use. Pull-up resistor is

built in.

Input for the clamp pulse. Clamps the signal

voltage during low interval. Pull-up resistor is

built in.

The clamp function is enabled when CLE = Low.

The clamp function is off and the device

functions as a normal A/D converter when CLE =

High. Pull-up resistor is built in.

Clock Input. Set to Low level when no clock is

input.

Analog Power Supply +5V.

Generates approximately +2.5V when shorted

with AVDD.

Reference Voltage (Top).

Reference Voltage (Bottom).

Generates approximately +0.6V when shorted

with AVSS.
