| MODULE Charge amplifier H4083 For radiation and high energy particle detection H4083 is a low-noise hybrid charge amplifier designed for a wide range of spectrometric applications including soft X-ray and low to high energy gamma-ray spectrometry. The first stage of this amplifier uses a low-noise junction type FET, which exhibits excellent performance when used with a photodiode having a large junction capacitance. H4083 is especially suited for use with Hamamatsu S3590/S3204 series, etc. Si PIN photodiodes. S3590 series photodiodes can be directly mounted on the backside of H4083, so there will be no increase in stray capacitance. H4083 is compact and lightweight, making detector design and development more flexible. Features Applications l Low noise l Compact and lightweight l Easy handling l Detection of X-rays, radiation, high energy particles s Specification Parameter Amplification method Input/output polarity Charge gain Noise characteristic Negative feedback constant Power supply Power consumption Configuration Dimensional outline Charge-sensitive type Inverted 0.5 V/pC 22 mV/MeV (Si) 550 electrons/FWHM 50 M//2 pF 12 V 150 mW 9-pin, single line type 24 (W) x 19 (H) x 4 (T) mm Specification s Equivalent circuit GAIN 2 pF THROUGH-HOLE B 50 M +12 V THROUGH-HOLE A 0.01 F IN OUT -12 V 1.5 pF , CAL GND , KACCC0019EA Charge amplifier s Pin connection H4083 Pin No. Symbol IN GAIN GND * CAL GND * -12 V +12 V GND * OUT Through-hole A P Through-hole B N * GND is internally connected. Input terminal Feedback constant adjustment terminal Input ground terminal Last pulse input terminal Power and output ground terminal Power terminal Power terminal Output ground terminal Output terminal Anode connection terminal Cathode connection terminal Content The left end pin is designated No. 1 when viewed from the component side with the pins facing downwards. q Using pin No. 2 Use pin No. 2 when changing the feedback constant which is typically 50 M/2 pF. Connect feedback resistance and capacitance between pin No. 2 and No. 9. Note that this connection is made parallel to the internal feedback resistance and capacitance. s Component side diagram q Changing the feedback resistance and capacitance If you want to change the feedback constant without making parallel connections, directly replace the resistor (Rf) and capacitor (Cf) shown at the right, which serve as feedback resistance and capacitance. Replacement components shoud be 2012 size. q Using through-holes A and B When H4083 is not covered with protective coating, a photodiode (such as S3590 series) can be directly soldered on the board. In this case, insert the photodiode leads into the throughholes from the solder side.
