Digital output function, current-to-voltage conversion amplifier for amplifying very slight photocurrent with low noise
C9329 is a current-to-voltage conversion amplifier used to amplify very slight photocurrent from a photodiode with very low noise. Three ranges
of photocurrent detection sensitivity level (H, M, L) are selectable to match the input signal. C9329 operates on the built-in dry batteries so it can
be easily used anywhere. C9329 can be directly connected to a personal computer through the RS-232C interface allowing you to acquire high-
resolution (16-bit) digital output signals and use the data logger function.
