C4675 series is a two-dimensional detector using a 16 16 (256) element Si PIN photodiode array that has high sensitivity in the visible range.
Current-to-voltage conversion amplifiers in the signal amplifier section are connected in parallel to each element of the photodiode array, thereby
allowing high-speed parallel signal processing.
C4675 series is also designed to suppress the power consumption so it operates from two power supplies (15 V).

Measurement method for frequency characteristics
The LED output was adjusted so that the output voltage Vo from C4675 series is set to 5 V. Under this condition, the output of
C4675 series was monitored by FFT while sweeping the LED drive frequencies.

Operating principle
When light enters a photodiode, photoelectric conversion
occurs in the photodiode and the photocurrent Ip is gener-
ated. The photocurrent Ip then flows through the current-to-
voltage conversion amplifier feedback resistance Rf and is
output as voltage V (=Ip Rf).
C4675 series uses current-to-voltage conversion amplifiers
connected to each of the 256-element photodiodes to per-
form parallel signal processing. A low noise bias circuit is
also used to reduce the photodiode junction capacitance.
