EL6272C - Product Brief

1-Ch Laser Diode Driver + Oscillator

Features

General Description

• 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.

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 I_INpin (virtu-

ally ground). The current seen at this pin is then amplified by 100X to

become a current source at pin I_OUT

• 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

An on-chip 500 MHz oscillator is provided to allow current modula-

tion when in read mode. This is turned on when the OSCEN pin is held

high. Complete control of amplitude and frequency is set by two exter-

nal resistors connected to ground at pins RFREQ and RAMP (see

graphs in this data sheet for further explanation).

Output write current pulses are enabled when an ‘L’ signal is applied

to the OUTEN pin.

The external resistor allows the user to accurately and independently

set the amplifier transconductance by applying a voltage to the set

resistor, without restriction on the voltage range, thus ensuring broad

voltage DAC compatibility. Alternatively, the I_INpin can be biased

from a current DAC or other current source.

Applications

• MO drives

• Mini-Disc drives

• Writable optical drives

• Laser diode current switching
