MPPC® modules GA type Optical measurement modules for low-level light detection, analog output The C14456 series (GA type) are optical measurement modules capable of detecting low-level light using its built-in TE-cooled MPPC for the visible to near infrared region. These modules consist of a thermoelectrically cooled MPPC, an amplifier, a highvoltage power supply circuit, and a temperature controller. The photosensitive area is available in two sizes of ϕ1.5 mm and ϕ3 mm, and the signal output is analog. The modules operate by supplying an external power supply (±5 V). As this product is compact and lightweight, it is suitable for integration into devices.

Dew condensation on the product may cause deterioration in characteristics and reliability. Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings. Recommended operating conditions Parameter Supply voltage*2 Condition Positive power supply Negative power supply *2: A power supply with 2 A or higher output must be used.
