Description

The OL2068 is an industrial power line driver and contains four identical short circuit proof differential line drivers up to 30 Volts driver supply with a joint enable function. 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 OL2068 package gives excellent thermal power dissipation, thus the usage in space limited applications is easy.
