SLC1610
Dual Channel
Linear Optocoupler
Description
The SLC1610 is an 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 SLC1610 an ideal
product for transformer replacement in many medical,
industrial and power supply isolation circuits. Its small size
makes the SLC1610 quite attractive for telecom
applications in which board space is limited.
The SLC1610 comes standard in a 16 SOIC package.
Applications
Power Supply Feedback
Transformer Replacement
