MAXIMUM RATINGS
The C7247 series is a DA type socket assembly designed for 28 mm (1-1/8 inch) diameter side-on and head-on
photomultiplier tubes. The C7247 series socket assembly incorporates a voltage-divider circuit and a current-to-voltage
conversion circuit along with an amplifier having a wide bandwidth (0 Hz to 5 MHz).
The C7247 series converts the low-level, high-impedance current of a photomultiplier tube into a low-impedance
voltage output by a factor of 0.3 V/ A.
Since the C7247 series employs an active voltage-divider circuit, it ensures an excellent DC linearity at low power
consumption.
a To be also practicable even with 5 V of input supply voltage except for narrow output range (2 V max).
