1024 channel Analog-to-Digital Converter
Model 1125/1125P
● Compatible with Windows
● Successive-approximation type 12 bit ADC
● Conversion time
- - - - - 10 μS
● Differential non-linearity - - - - - Less than +/- 2%
● Integral non-linearity

Clear Pulse 1125 1k ADC is suitable for pulse height analysis of
scintillation detectors, SSD alpha spectrometer, etc., which do not
requires state of the art level resolution.
1125 adopts 12 bit successive-approximation type ADC chip and
provides upper 10 bits as digital pulse height data output. Input
signal above threshold level is routed to peak-hold circuit and 12
bits ADC converts analog signal to digital signal, then generates
upper 10 bits content as output data.
Differential non-linearity (with compensation circuit) is less than
+/- 2 % and integral non-linearity is less than +/- 0.05 % over full
scale.
1125 is designed so as PC provides control function and data
memory function.
Clear Pulse prepares standard application software and I/O
interface (PCI bus compatible) for Windows.
1125 is housed in a NIM-standard single-width module.
1125P is housed in a tabletop box, which contains
internal power supply.
