DS3923 Datasheet (Maxim Integrated) - High-Speed Current Mirror

DS3923, High-Speed Current Mirror

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.

DS3923 Features

* an external shutdown. An integrated FET is also provided which can be used to quickly clamp the high-voltage bias to ground in the case of high optical input power. The DS3923 is available in a 24-pin TQFN package and operates over an extended temperature range of -40°C to +95°C. Applications
