C5331 Datasheet, PDF (1/4 Pages) Hamamatsu Corporation – Operates an APD with single 5 V supply

MODULE
APD module
C5331 series
Operates an APD with single 5 V supply
Features
Applications
l Choice of high sensitivity APDs
l APD evaluation
l A total of 11 types are available, including 6 types of 800 nm band APDs with Spatial light transmission
l active areas from φ0.2 to φ5 mm, 3 types of short-wavelength APDs with active Bar code readers
areas from φ1 to φ5 mm, and FC connector types.
l Laser radars
l High sensitivity detection board optimized for APD evaluation
l Optical rangefinders
l An APD and high-speed current-to-voltage amplifier circuit are mounted on a Optical communications
compact board. The high-speed current-to-voltage amplifier circuit features a
low-noise configuration ideal for the APD signal readout and operates at high
speeds yet with high sensitivity.
l Easy handling
Single 5 V supply operation
l Built-in temperature-compensated bias voltage circuit
Controls the bias voltage with a thermosensor to keep the APD gain constant.
Gain is stabilized to as low as ±2.5 % Typ. at ambient temperatures of 25 ±10 ˚C.
Ripple noise usually inherent to high voltage power supplies is also minimized.
l Compact and lightweight
The circuit board is no larger than business card size, and weighs only 52 g.
l Low price
l Custom devices available with different dimensions and specifications
