General Description
The EL6272C is a single channel laser diode current amplifier that provides controlled current to a grounded laser diode. The amplifier can provide up to 200 mA of DC or pulsed current with switching speeds of approximately three nanoseconds rise/fall time. The level of the output current is set by an analog voltage applied to an external resistor which converts the voltage into a current at the IIN pin (virtually ground). The current seen at this pin is then amplified by 100X to become a current source at pin IOUT.

Features
• Voltage-controlled output current source (requiring one external set resistor)
• Current-controlled output current source.
• Rise time = 3.0 ns typ.
• Fall time = 3.5 ns typ.
• On-chip oscillator w/frequency and amplitude control by use of external resistors to ground.
• Oscillator to 500 MHz typ.
• Oscillator to 100 mA pk/pk typ.
• Single +5V supply (±10%)
• Current amplification = 100
• TTL/CMOS control signals

Applications
• MO drives
• Mini-Disc drives
• Writable optical drives
• Laser diode current switching
