CMOS linear image sensors
S8377/S8378 series
Built-in timing generator and signal process-
ing circuit; 5 V single supply operation
The S8377/S8378 series is a family of CMOS linear image sensors designed for image input applications. These linear image
sensors operate from 5 V single supply with only start and clock pulse inputs, making them easy to use. The signal process-
ing circuit has a charge amplifier with excellent input/output characteristics and allows signal readout at 500 kHz.
The photodiodes of the S8377 series have a height of 0.5 mm and are arrayed in a row at a spacing of 50 μm. The photo-
diodes of the S8378 series also have a height of 0.5 mm but are arrayed at a spacing of 25 μm. The photodiodes are avail-
able in 3 different pixel quantities for each series: 128 (S8377-128Q), 256 (S8377-256Q, S8378-256Q), 512 (S8377-512Q,
S8378-512Q) and 1024 (S8378-1024Q). Quartz glass is the standard window material.
