® EL6833 www.DataSheet4U.com Data Sheet July 15, 2004 FN7350.1 Dual 4-Channel Driver with Oscillator & LVDS The EL6833 is a high performance, dual output, laser driver for writeable ‘super-combo’ CD - DVD drives.

The ENA pin enables the chip, while the SEL1 pin selects the IOUT pin.

Various waveforms can be generated where the amplitude is determined by the currents flowing into IINR, IIN2, IIN3, and IIN4.

The timing is determined by the signals at WEN2-WEN2B, WEN3-WEN3B, and WEN4-WEN4B.
