LMH6533 4-Channel Laser Diode Driver

The LMH™ 6533 is a laser diode driver for use in combination DVD/CD recordable and rewritable systems. The part contains two high-current outputs for reading and writing the DVD (650 nm) and CD (780 nm) lasers. Functionality includes read, write and erase through four separate switched current chann.

LMH6533 Features

* a 150 mA read channel plus one 300 mA and two 150 mA write channels, which can be summed to allow a total output current of 500 mA or greater. The channel currents are set through four independent current inputs. The part is manufactured in National Semiconductor’s VIP10™ process, which features bon
