Product Description
Product Overview
This IR receiver series is optimized for long burst remote control systems in various environments. Featuring individual IC settings for maximum performance and enhanced immunity against noise from sources like lamps, LCD TVs, and Wi-Fi, these devices offer a low supply current and integrate a photo detector and preamplifier in a single package. They operate within a supply voltage range of 2.0 V to 5.5 V and are suitable for infrared remote control systems. The demodulated output signal can be directly connected to a microprocessor for decoding.
