General Description
The DS1842 integrates the discrete high-voltage com-
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 cur-
rent through the APD and also features an external
shutdown. The device also includes a dual current mir-
ror to monitor the APD current.
