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
shorted with AVDD.
Reference Voltage (Top).
+2.5V
Reference Voltage (Bottom).
Generates approximately +0.6V
shorted with AVSS.
