LMH6525 Overview
The LMH™6525/6526 is a laser diode driver for use in bination 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 channels.
