Dual 4-Channel Driver with Oscillator
The EL6838 is a high performance, dual output, laser driver for writeable ‘super-bo’ 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 OUTEN2, OUTEN3, and OUTEN4. The oscillator is enabled when OSCEN is high. The amplified IINR current of the selected channel is enabled when the ENA pin is high. The total output current is the sum of the read current, the enabled write...
