Driver circuit for voltage-output type NMOS linear image sensor
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).
• Suitable for voltage-output type image sensors
• Compact (compared to conventional type C4074)
• Single power supply (+12 V or +15 V) operation
