ATR0842 Datasheet - ATMEL

ATR0842 4-channel LVDS Laser Diode Driver

The ATR0842 is a laser diode driver designed to operate two differently grounded laser diodes. The output, IOUTA, can be used for a blue laser diode (400 nm) with up to 6 V voltage drop by applying 8 V at pin VCCH. The other output, IOUTB, supports legacy laser diodes for DVD-RW/+RW/RAM (650 nm) and.
