Digital Isolation For A / D, D / A Conversion

The TOSHIBA TLP2631 dual photocoupler consists of a pair of GaAℓAs

light emitting diode and integrated high gain, high speed photodetector.

This unit is 8-lead DIP.

The output of the detector circuit is an open collector, Schottky clamped

transistor.

A Faraday shield integrated on the photodetector chip reduces the effects

of capacitive coupling between the input LED emitter and the high gain

stages of the detector. This provides an effective common mode transient

immunity of 1000V / μs.
