PHOTODIODE
16 × 16 element photodiode array detector
C4675 series
2-D detector using 256-element photodiode with visible sensitivity
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.
