Sync separated SYNC signal output.
Separates and outputs the SYNC
signal from SYNC ON GREEN input
signal.
(SYNC signal input from SYNCIN1
and SYNCIN2 pins can be output.)
Both positive and negative polarity
outputs are supported.
The polarity is selected by the control
register.
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 820 resistor
should be connected between these
pins and GND to monitor high
frequency signals.
When not used, connect to AV
SYNC ON GREEN signal inputs.
Input via a 0.1µF capacitor.
When not used, connect to AV
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.
Power supply for amplifier block.
GND for amplifier block.
