Description

The M61880FP is a laser diode driver/controller that performs drive and laser power control of a type of semiconductor laser diode in which the semiconductor laser diode anode and monitoring photodiode cathode are connected to the stem.

The M61880FP has a sink type laser drive current output pin, is capable of high-speed switching at up to 200 Mbps, and can drive a laser diode at a maximum drive current of 100 mA (drive current = switching current + bias current).

A high-speed sample-and-hold circuit is incorporated, enabling a self-APC* system to be implemented without the need for laser power control from outside.

* Automatic Power Control
