General Description

The DS3920 precision current mirror is designed for avalanche photodiode (APD) and PIN photodiode biasing and monitoring applications.

The device offers a current clamp to limit current through the APD and a current mirror output that produces a signal proportional (5:1) to the APD current.

A diode is also provided to limit the voltage at the current mirror output.
