CMOS Sensor Inc., Cupertino, CA, offers the C640 linear image sensor with 4000 photodiode elements. The device uses a 7 by 7 µm pixel size integrated with a programmable gain amplifier, 12-bit ADC, voltage regulator, low voltage differential amplifier, and timing generator and provides a 28 mm imaging length. Thermal noise is <2 LSB, saturation is 4096 LSB for a dynamic range of more than 2000:1. Other features include reduced fixed-pattern noise, auto dark voltage cancellation, snap shot operation, image processing function controls, and destructive readout, nondestructive readout, or power-down output modes.
