Description

Reference voltage (bottom)

Connect to AVSS for normal use.

When another external voltage is input,

connect an external 0.1µF capacitor and

retain a 1.5V differential compared to the

top reference voltage.

Reference voltage (top)

By setting VRB to AVSS, outputs

approximately 1.5V.

Connect only a 0.1µF external by-pass

capacitor for normal use.

When another external voltage is input, it

must be 2.2V or lower.

Analog GND.

Switches the input of the 3x amplifier.

When SEL is at Low level, VIN1 is selected.

When SEL is at High level, VIN2 is selected.

Standby function ON/OFF selector.

In standby state when High.

Fix to VSS for normal use.

When CLE = Low: Clamp functiion is

enabled.

When CLE = High: Clamp function is

disabled, and only the normal A/D

converter function is enabled.

Clock input

Inputs the clamp pulse to Pin 20 (CLP).

Clamps the High interval signal voltage.

Digital GND.

D7 (MSB) to D0 (LSB) output

Outputs Low level in standby.

In operation, the phase of D7 to D0

output is inverted against the phase of

ADIN.

5V or 3.3V
