Description

Amplifier output signal monitor.

Each monitor can output either the

entered signal immediately before

A/D converter or the signal after

switching between 2 types of input

signals. The 2 types of input signals

can be selected by the control

register and output.

These pins are emitter follower

outputs, but the internal bias current

is so small that a 820Ω resistor

should be connected between these

pins and GND to monitor high

frequency signals.

When not used, connect to AVCCAMP.

Power supply for amplifier block.

GND for amplifier block.

Both positive and negative polarity

outputs are supported.

SYNC ON GREEN signal inputs.

Input via a 0.1µF capacitor.

When not used, connect to AVCC.

The SYNC TIP clamp level is

approximately 2.0V + Vf (0.8V) =

approximately 2.8V. At this time, if

the pin voltage is lowered, these pins

go to low impedance and current

flows from the IC.

When these pins are at the SYNC

TIP level or higher, the clamp circuit

is off and only an input base current

of approximately 1.2µA flows.
