Description

Clamp reference voltage input.

Clamps to provide a clamp period

input signal equal to the reference

voltage.

DVSS

Integrates the voltage for clamp

control.

CCP and VIN voltage changes are in

positive phase.

Digital ground.

CLAMP

PULSE

When CLE is at low, clamp function is

activated.

When CLE is at high, clamp function

is OFF and only the usual A/D

converter function is active.

By connecting CLE pin to DVDD via a

several hundred Ω resistance, the

clamp pulse can be tested.

When OE is at low, Data is output.

When OE ia at high, D0 to D7 pins

turn to high impedance.
