Hamamatsu C12703-01 Apd module Datasheet

APD modules
C12703 series
APD module integrated with peripheral circuits
Features
Applications
Uses a high sensitivity APD
Two types of APDs with different photosensitive areas
(1.5 mm, 3.0 mm) are provided.
Evaluation of APD
On-board high sensitivity circuit optimized for APD
evaluation. An APD and a low-noise current-to-voltage
amplifier circuit are mounted on a compact PC board.
The current-to-voltage amplifier circuit features a lownoise configuration allowing low-light-level detection.
Fluorescence measurement
Bar code readers
Particle counters
Film scanners
Detects optical signals from fixed light (DC light)
The C12703 detects optical signals from fixed light (DC
light) to 10 MHz pulsed light making it well suited for bar
code readers and film scanners. The C12703-01 covers
a narrower bandwidth from fixed light (DC light) to 100
kHz pulsed light, but provides an excellent NEP of 20 fW/
Hz1/2, in the room temperature, making it suitable for
fluorescence measurement and particle counters where
low-light-level detection is essential.
Built-in temperature-compensated bias power supply.
The bias power supply is controlled with a thermosensor to keep the APD gain constant. Gain variations are
typically held within ±2.5% at an ambient temperature of 25 ±10 °C. Ripple noise usually inherent to
high-voltage power supplies is also minimized.
Compact and lightweight
The board is no larger than a typical business card.
Low price
Custom designed module with different dimensions
and specifications are available.

Precaution
(1) This product incorporates a high-voltage power supply. To prevent electrical hazards, do not remove the mold material.
(2) Recommended termination resistance for this module is from 10 k to 1 M.
Terminating with a low-resistance resistor such as 50  affects the output drive capacity, and may cause poor linearity.
