Overview
DS3923
EVALUATION KIT AVAILABLE
High-Speed Current Mirror with Sample/Hold Output
General Description
The DS3923 high-speed current mirror integrates highvoltage devices necessary for monitoring the burst-mode receive power signal in avalanche photodiode (APD) biasing and optical line terminal (OLT) applications.
It provides small and large gain current mirror outputs to monitor the APD current.
A sample/hold circuit with automatic gain selection captures the sampled signal so that an external ADC can accurately measure the signal.
An adjustable current clamp limits current through the APD.
The clamp also features an external shutdown.
An integrated FET is also provided which can be used t...
