LMH6526, LMH6525, Four-hannel Laser Diode Driver
The LMHâ˘6525/6526 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 c
LMH6526 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 600 mA or greater. The channel currents are set through four independent current inputs. An on-board High-Frequency Modulator (HFM) oscillator helps reduce low-frequency noise
