Dual 4-Channel Driver with Oscillator &

LVDS

Features

• Two channels for CD or DVD

The EL6835 is a high performance,

dual output, laser driver for writeable

• Voltage-controlled output current source requiring one

external set resistor per channel

ENA pin enables the chip, while the SEL1 pin selects the

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 currents, and the oscillator current

when enabled.
