Photo-IC Illuminance Sensor (linear output type)TPS818
Overview
TPS818 photo-IC linear output (current output type) which integrates photodiode current circuit onto single chip. luminous efficiency correction filter mounted detector ensures accurate luminosity output levels. device's excellent output linearity enables automatic adjustment luminosity screen monitor accordance with ambient brightness operating environment.
Features
Photodiode current circuit integrated onto chip High sensitivity Light current 240µA (typ.) value approximately x22500 that photodiode with same detector area. value approximately that phototransistor with same detector area. Reduced light current variation Minimum-to-maximum range (±25% typical rating) 1.67 times width. Output linearity illumination excellent Output voltage load resistance. luminous efficiency correction filter mounted detector; hence, accurate luminosity levels output. (typ.) device normally unaffected light output short-infrared LED. current consumption (max) @VCC Environmentally-friendly silicon used chip material. suitable replacement from CdS.)
Applications
Luminosity adjustment screens, monitors liquid-crystal monitors Notebook portable information devices Cellular phones Home appliances
