Sensor IC for centre detection of a light source.

PR5510 consists of two triplets of triangular photodiodes with reciprocal orientation, together with a differential transimpedance amplifier. If illuminated uniformly, the output is Vcc/2, but depends on the balance of illumination of the triplets.

APPLICATIONS
• Light beam alignment
• Optical potentiometers
• Vibration sensors
• Optical position detectors
