General Description

The EL6258C is a high-performance three channel laser diode current amplifier that provides controlled current to a grounded laser diode. Channels 2 and 3 must be used as the write channels, with switching speeds of approximately one nanosecond rise/fall time.

Features

• High-performance laser diode driver

• Voltage-controlled output current source requiring one external set resistor per channel

• Current-controlled output current source

• Rise time = 1.0ns

• Fall time = 1.1ns

• On chip oscillator with frequency and amplitude control by use of external resistors to ground

• Oscillator to 500MHz

• Oscillator to 100mA pk/pk

• Single +5V supply (±10)

• Current amplification = 100

• Disable feature for power-up protection and power savings

• TTL/CMOS control signals

• Fast settling APC amplifier

Applications

• DVD drives
