SLC800
Linear Optocoupler
DESCRIPTION
The SLC800 is a highly advanced linear optocoupler device. The product takes advantage of highly matched transistors used for both a
Servo Feedback Loop and a Forward Output Loop. The closely matched transistors provide a high degree of linearity across a wide range
of input signal variation. These features make the SLC800 an ideal product for transformer replacement in many medical, industrial and
power supply isolation circuits. Its small size makes the SLC800 quite attractive for telecom applications in which board space is limited.
