Overview: .. IMAGE SENSOR Driver circuit for NMOS linear image sensor C7885 series Driver circuit for voltage-output type NMOS linear image sensor C7885 C7885 series is a driver circuit specifically designed for the Hamamatsu voltage-output type NMOS linear image sensors (S3921 to S3924 series). NMOS linear image sensors are self-scanning photodiode arrays integrated with a scanning circuit of N-channel MOS transistors. C7885 series supplies start pulses, 2-phase clock pulses and reset pulses necessary for voltage-output type image sensor operation. C7885 series also includes a signal processing circuit that inverts and amplifies video signals from an image sensor. C7885 series operates by input of a master start pulse, master clock pulse and connection to a power supply (+12 V or +15 V). C7885-20 is multichannel detector head incorporating driver circuit (C7885) developed for Hamamatsu NMOS linear image sensor. C7885-20 is designed especially for pactness, having an overall length as short as 40 mm or less. The housing case also provides a shielding effect against external noise. As useful options, peripheral devices are available for driving C7885-20, and for the output signal processing.
