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
• CD-RW applications
• Writable optical drives
• Laser diode current switching
