Laser Diode Driver

with Light Power Control

AD9661A

and fall times are 2 ns to complement printer applications that

use image enhancing techniques such as pulse width modula-

tion to achieve gray scale and resolution enhancement. Control

signals are T T L/CMOS compatible.

FEATURES

< 2 ns Rise/ Fall Tim es

Output Current: 120 m A

Single +5 V Pow er Supply

Sw itching Rate: 200 MHz typ

Onboard Light Pow er Control Loop

T he driver output provides up to 120 mA of current into an

infrared N type laser, and the onboard disable circuit turns off

the output driver and returns the light power control loop to a

safe state.

APPLICATIONS

Laser Printers and Copiers

T he AD9661A can also be used in closed-loop applications in

which the output power level follows an analog POWER LEVEL

voltage input. By optimizing the external hold capacitor and

the photo detector, the loop can achieve bandwidths as high as

25 MHz.

GENERAL D ESCRIP TIO N

T he AD9661A is a highly integrated driver for laser diode appli-

cations such as printers and copiers. T he AD9661A gets feed-

back from an external photo detector and includes an analog

feedback loop to allow users to set the power level of the laser,

and switch the laser on and off at up to 100 MHz. Output rise

T he AD9661A is offered in a 28-pin plastic SOIC for

operation over the commercial temperature range (0°C to

+70°C).
