C4675

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).

The photocurrent Ip then flows through the current-tovoltage 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 perform parallel signal processing. A low noise bias circuit is also used to reduce the photodiode junction capacitance.
