EU-38-TTL
TECHNICAL DATA
Laser Diode Driver
Features
⢠constant laser diode current adjustable with potentiometer
⢠modulation input
⢠laser diode output power independent from supply voltage
Specification
⢠dimension: 35 x 15 mm² (+/- 0.5 mm)
⢠supply voltage: 4.0 - 5.0 VDC
⢠max laser diode current: 1 A
⢠modulation frequency: DC .. 100 kHz, analog and digital voltage input
⢠modulation input voltage:
0 V = laser off, UB = laser on, any voltage between 0 and UB possible (>2 V = high)
P1
Ub (supply voltage +)
GND (supply voltage -)
modulation input
laser diode anode (+)
laser diode cathode (-)
CAUTION
for high currents
use a heat sink
transistor gets hot
P1: trim pot for laser diode current adjustment
ï¨ turn left = laser diode current increase
ï¨ turn right = laser diode current decrease
Note: P1 is a trim pot which can be turned clockwise and counterclockwise slowly to the end
points. The trim pot can be damaged, if you keep on turining it at the end point !
