Depending on your application, the SPMArray4 is also available with multi-channel preamplification electronics and an evaluation board for pixelated/summed pixel output.

SPMArray4-A0 Pre-amplifier Electronics Features

SPMArray4: Scalable silicon photomultiplier array for large area detection with electronics

  • Compact small foot print electronics (13.6mm x 147.6mm) with form factor match to SPMArray4 width for tiling of arrays/electronics
  • 16 channel differential pre-amplifier design based on the AD8132
  • Amplifier power supply +/-3.3V default (range from +/-2.7V to +/-5V absolute maximum)
  • Differential pre-amplification output for each pixel with common mode voltage at ground for low cross talk
  • Compact pre-amplification differential output via 50 way FFC (flat flexible cable) or 80 way board to board connector
  • Power input via the FFC, 4 way Sherlock connector or board to board connector
  • SPI interface for programming bias to pixels available via IDC cable header, FFC or board to board connector for direct programming from Diolan SPI programmer
  • Read back monitor of programmed bias voltage on FFC or board to board connector
  • Positive Input bias supply: +34V to +40V (50mA maximum) supply which is stepped down and regulated on the amplifier board to bias the pixels
  • Power supply select jumpers:
  • Jumper to bypass pre-amplifier bias regulator and to apply direct bias to the SPMArray from a bench supply for example
  • Jumper allows the regulator to be supplied from the board to board connector/FPC connector or the Sherlock connector
  • Board to board 80 way 0.5mm pitch connector for plugging into SPMArray4-A1 evaluation module (differential output signals, power supply, bias supply, stepped down bias monitor, SPI interface).

  • Allows fast evaluation of SPMArray4 and pre-amplifier board
  • 16 individual SMA sockets for monitoring on an oscilloscope for example
  • Summed pixel output on an SMA connector
  • Board to board 80 way 0.5mm pitch connector for plugging into SPMArray4-A0 (differential output signals, power supply, bias supply, stepped down bias monitor, SPI interface).
  • 6V DC power supply provided by a universal AC adapter
  • On board regulation to provide +/-3.3V pre-amplifier supply
  • On board switching regulator to provide +36V input to the step down regulator on the preamplifier board.
  • FFC connector should remote positioning of the evaluation board from the pre-amplifier board be required (e.g. for environments where there are strong magnetic fields)
