AD9660

GENERAL DESCRIPTION

The driver output provides up to 180 mA of current @ 3 V,

90 mA of BIAS current, 60 mA of modulation current, and

30 mA of offset current. The onboard disable circuit turns off

the output drivers and returns the light power control loops to a

safe state.

The AD9660 is a highly integrated driver for laser diode appli-

cations such as optical disk drives, printers, and copiers. The

AD9660 gets feedback from an external photo detector and in-

cludes two analog feedback loops to allow users to set “bias”

and “write” (for optical disk drives) power levels of the laser,

and switch between the two power levels at up to 200 MHz.

Output rise and fall times are typically 1.5 ns and 2.0 ns to

complement printer applications that use image enhancing tech-

niques such as pulse width modulation to achieve gray scale,

and allow disk drive applications to improve density and take

advantage of pulsed write formats. Control signals are TTL/

CMOS compatible.

The AD9660 can also be used in closed loop applications in

which the output power level follows an analog WRITE LEVEL

voltage input. By optimizing the external hold capacitor, and

the photo detector, the write loop can achieve bandwidths as

high as 25 MHz.

The AD9660 is offered in a 28-pin plastic SOIC for operation

over the commercial temperature range (0°C to +70°C).
