LED Driver with  
Programmable Prebias Voltage  
General Description  
Features  
The MAX3966 is a programmable LED driver for fiber  
optic transmitters operating at data rates up to  
266Mbps. The circuit contains a high-speed current  
driver with programmable temperature coefficient  
(tempco), adjustments for LED prebias voltage, and a  
Programmable LED Prebias Voltage  
Single +3V to +5.5V Power Supply  
Complementary Output Reduces Supply Noise  
Adjustable Modulation Current  
V
reference voltage generator. The circuit accepts  
BB  
PECL data inputs, and operates from a single +3V to  
+5.5V power supply.  
Adjustable Temperature Compensation  
Available in 16-Pin/24-Pin QSOP or Die  
The MAX3966 can switch up to 100mA into typical  
high-speed light-emitting diodes. As temperature  
increases, the device’s modulation current increases  
with a tempco that is programmable from 2500ppm/°C  
to 12,000ppm/°C. The modulation current is pro-  
grammed with a single external resistor.

The MAX3966’s LED prebias voltage is programmable  
from 400mV to 925mV. The prebias circuit produces  
peaking current, which improves the LED switching  
speed.  
*Some features are not available in the 16-pin QSOP package.  
Contact factory for information and availability.  
**Dice are designed to operate over a 0°C to +100°C junction  
temperature (Tj) range, but are tested and guaranteed only at  
Complementary current outputs help to maintain a con-  
stant supply current, reducing EMI and supply noise  
generated by the transmitter module. The MAX3966 is  
available in die form, or in 16-pin and 24-pin QSOP  
packages.
