Output A
Output A-
The OL2068 is an industrial power line
driver and contains four identical short cir-
cuit proof differential line drivers up to 30
Volts driver supply with a joint enable func-
tion. An internal 5 V power supply is used
as reference and supply voltage for the
circuitry and is able to supply max. 5mA
for external 5V components like a sensor
or a constant current source for an LED.
The very small outline TSSOP package
gives excellent thermal power dissipation,
thus the usage in space limited applica-
tions is easy.

Note on OL2068:
MON 10
11 C IN
The 4 GND pins do not need to be connected to electrical GND simultaneously. One of them tied to GND is enough. However - for
heavy driving of loads it is recommended to tie all four pins to GND.
The internal voltage regulator (Pin 5,Vcci) can be used for external loads (5mA max.) as well. Please make sure, that a decoupling
capacitor of min. 100nf is connected to Vcci. If, due to heavy loads, the internal voltage supply will be rippled, please increase the
capacitor value to stabalize Vcci.
