6. Remote Control Receptor: Photo IC

¢ Overview

PNJ4805M is a low-current-consumption type infrared remote control receptor photo IC. Multi-voltage compatible (VCC = 2.7 V

to 5.5 V), so current consumption is reduced compared to previous products.

Can be used for a wide range of remote-control applications, such as digital equipment like TVs, DVD equipment, etc., home

appliances such as air conditioners, etc., and game equipment or electronic toys, etc.
