Hermetic Surface Mount Isolinear Optocoupler

The OLS700 linear optocoupler consists of one LED that is optically coupled to two matched photodiode detectors. Photodiode detectors are used for excellent linearity.

A fixed relationship is maintained between input and output due to:
  • The photodiode on the input side acts as a feedback device that permits an external feedback loop to ensure constant LED light output.
  • A similar matching photodiode on the output side is used to drive an output circuit that is electrically isolated from the input.
Each OLS700 is mounted and coupled in a custom hermetic surface mount leadless chip carrier (LCC) ceramic package that provides 1000 VDC electrical isolation between the input and output.

Device mounting is achieved with reflow soldering or conductive epoxies.
