  29. Transmitter / Application Circuit with +5V ECL Inputs

  30. Un exemplu : WLD3343 GENERAL DESCRIPTION The WLD3343 is a general-purpose analog hybrid circuit for use in ultrastable laser diode driver applications. The WLD3343 maintains precision laser diode current (constant current mode) or stable photodiode current (constant power mode) regulation using electronics that are compatible with any laser diode type. Supply up to 2 Amps of current to your laser diode from a single +5 Volt power supply. Connect two or more WLD3343 units together to drive higher output currents.
