For a single detector, you can use a relatively expensive module. For a large detector array, you need to develop an ASIC. For a moderate number of detectors, you can use an inexpensive circuit that ...

The 16-V zener diode protects Q1’s base from excessive voltage. Designers can use a 12-V zener to match the operating voltages exactly, but the 16-V diode adds a 4-V margin of flexibility in the ...
