TOSHIBA CCD LINEAR IMAGE SENSOR CCD(Charge Coupled Device)
TCD1001P
The TCD1001P is a high sensitive and low dark current
128-elements linear image sensor which includes CCD drive
circuit, clamp circuit and sample & hold circuit.
The CCD drive circuit consists of the pulse generator therefore it
is possible to easy drive by applying simple pulses. The sensor is
designed for scanner.
