® EL6836 Data Sheet July 1, 2003 FN7351 PRELIMINARY Dual 4-Channel Driver with Oscillator The EL6836 is a high performance, dual output, laser driver for writeable 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 WEN2B, WEN3B, and WEN4B.

The oscillator is enabled when OSEN is high.
