Description

Clamp reference voltage input.

Clamps so that the reference voltage

and the input signal during clamp

interval are equal.

Integrates the clamp control voltage.

The relationship between the changes

in CCP voltage and in VIN voltage is

positive phase.

Digital ground

CLAMP

PULSE

The clamp function is enabled when

CLE = Low.

The clamp function is set to off and

the converter functions as a normal

A/D converter when CLE = High.

The clamp pulse can be measured by

connecting CLE to DVDD through a

several hundred Ω resistor.

Data is output when OE = Low.

Pins D0 to D7 are at high impedance

when OE = High.
