DS1842 Datasheet Bias Output Stage

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-4557; Rev 0; 4/09 .. 76V, APD, Bias Output Stage with Current.

General Description

The DS1842 integrates the discrete high-voltage ponents necessary for avalanche photodiode (APD) bias and monitor applications.

A switch FET is used in conjunction with an external DC-DC controller to create a boost DC-DC converter.

A current clamp limits current through the APD and also
