The power supply for Ch.1 and 2 is supplied from Pin20 and the power supply for Ch.3 and 4 is supplied from Pin9
independently.
Output amplitude is increased by increasing the supply voltage. Set the power supply voltage as necessary. However, always set
Pin7 of V
CC
to the maximum electric potential.
Pin8 and 21 may require a capacitor for ripple removal.
As protection functions, V
CC
reset circuit,V
REF
detector and heat protection circuit are incorporated.
The V
CC
reset circuit operates at approx. 3V and is released at 3.2V, when the supply (Pin7) decreases. For the V
REF
detector, the
protection function works at approx. 1V (max. 2V).
Also, the set temperature for operation of the heat protection circuit is approx. 180C .
PC (Power Cut) functions which can be independently controlled are incorporated in Ch.1 and 2.
5V Supply
By adding an external PNP transistor, 5V regulator can be constructed. Attach an external capacitor for loop filter to output Pin2.
In Pin1, the base current limiting circuit (typ. 10mA) is incorporated.
When the V supply is used, the external PNP Tr emitter must be connected to pin than Pin7 (SV
CC
pin)
OP Amp.
When the operational amplifier is not used, make connection as follows ;
