Description

Generates approximately +2.5V

when shorted with AVDD.

Reference voltage (top)

Reference voltage (bottom)

Generates approximately +0.6V

when shorted with AVSS.

Analog input

Analog ground

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

Data is output when OE = Low.

Pins D0 to D7 are at high

impedance when OE = High.

Pull-down resistor is built in.
