AMPLIFIER MODULES
M7279, M8879
The M7279 and M8879 are non-inverting amplifier modules,
specifically designed for photodetectors such as photomulti-
plier tubes. These amplifier modules work with either a cur-
rent or voltage input, allowing direct connection to a photo-
multiplier tube or other photodetectors. The M7279 is com-
prised of an 8-pin SIP (single inline package) type hybrid IC
with protective epoxy resin and the M8879 is a 10-pin hybrid
IC to allow a compact mounting size on PC board. The offset
voltage and gain are easily adjusted by connecting an exter-
nal variable resistor.
