EL6270C - Product Brief

Laser Driver with Ocillator and APC

Features

General Description

• Low output noise = 4.0nA/rt-Hz

• High-performance laser diode

driver

The EL6270C is a high-performance single channel laser diode power

regulator and oscillator for a grounded cathode laser diode and photo-

diode system. The EL6270C’s APC (Automatic Power Controller) will

set the average laser diode input current for a desired average photo-

diode output current. The APC can provide up to 100 mA of DC

current.

• Pin compatible with EL6257

• Voltage-controlled output current

source to 150 mA per channel,

requiring one external set resistor

per channel

• Current-controlled output current

source to 150 mA per channel

• Rise time = 1.0 ns

• Fall time = 1.1 ns

• On chip oscillator with frequency

and amplitude control by use of

external resistors to ground

An on-chip programable oscillator is provided to allow current modu-

lation of the output laser current. Two external resistors control of

amplitude and frequency. The Oscillator can provide up to 100mA

pk/pk.

A disable function is included which reduces supply current to less

than 5µA.
