Overview
Sipm comp is an open-source printed circuit board by SvalbardHAB, from the SvalbardHAB/SiPMADC repository on GitHub. It is a 4-layer board of 63 × 50 mm with 119 parts on 148 nets, routed with 1,357 tracks and 212 vias.
It is built around the LD3985M47R and MBR0540. Its parts include 54 capacitors, 24 resistors, 9 ICs, 9 connectors and 5 diodes. It belongs with the FPGA and CPLD boards of this library.

README
README.mdExisting SiPM ADC board
This board contains two dual-channel 10 bit 65MSPS MAX1182 ADCs; kindly provided by Maxim as free samples. There is also a MachXO2 CPLD for data processing, interfacing over SPI with a microcontroller. It is designed to obtain more quantitative data from the SiPM and scintillator detector than the previous comparator board; at the expense of only using four of the 16 channels.
The board also contains the SiPM bias supply, consisting of a -34V inverting buck-boost converter and an op-amp to output the exact voltage. This, along with the midpoint voltage - note this is not how the board is designed; during assembly a wire connecting Vmid to one of the DAC channels was added and U1 was not populated - is set by a TI DAC7564 allowing precise closed-case software adjustment.
At present the board has been assembled and tested. Unfortunately one of the ADC channels is not functioning correctly and needs to be investigated further; this is suspected to be an assembly issue.
