Application hints:
Bias supply voltage
Current limiting resistor
APD
min. 0,1 µF,
closest to APD
• Current should be limited by a protecting resistor or current limiting - IC
inside the power supply
• For low light level applications blocking of ambient light should be used
• For high gain applications bias voltage should be temperature compensated
• Please consider basic ESD protection while handling
• Use low noise read-out - IC
• For further questions please refer to document "Instructions for handling and processing"
• Optimum gain: 50-60
Diode, protective circuit
Read-out circuit or
f.e. 50 Load resistance
Package dimension:
Small quantities: Foam pad, boxed (12 cm x 16.5 cm)
