General Description
The EL6275C is a four channel laser diode current amplifier that provides controlled current to a grounded laser diode. Channels 2, 3, and 4 should be used as the write channels, with switching speeds of approximately three nanosecond rise/fall time.

Features
• Shrink-Small Outline Package
• Voltage-controlled output current source requiring one external set resistor per channel
• Current-controlled output current source
• Rise time = 3.0ns
• Fall time = 3.5ns
• 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

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