OPA2048CA
Self-Scanning Line Sensor
GENERAL DESCRIPTION
The OPA2048CA is a 2,048-bit, one-dimensional diode array comprised of PN junction
photodetector diodes and CCDs (charge coupled devices). By using a two-phase clock pulse,
transfer pulse, and reset pulse, the OPA2048CA can measure incident light.
FEATURES
• Dynamic range: TYP 500
• CCD for high sensitivity
• CCD transfer efficiency greater than 99.995%
• Photodetector configured of PN junction photodetector diodes for good blue sensitivity and
good output uniformity.
• Photodiodes highly integrated with 13 µm pitch for high resolution
• High-speed scanning
• Low-voltage operation
• Internal output amplifier and compensating amplifier
APPLICATIONS
• Facsimiles
• OCRs
• Industrial control
• Monitoring devices
• Object recognition
• Measurement devices
