Remote Receiver Sensor 38.0kHz 45m Through Hole This IR receiver series is optimized for long burst remote control systems in different environments. The customer can chose between different IC settings (AGC variants), to find the optimum solution for his application. The higher the AGC, the better noise is suppressed, but the lower the code compatibility. The devices contain a PIN diode and a preamplifier assembled on a lead frame. The epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding. These components have not been qualified to automotive specifications. Individual IC settings to reach maximum performance • Immunity against noise (lamps, LCD TV, Wi-Fi) • Low supply current • Photo detector and preamplifier in one package • Supply voltage: 2.0 V to 5.5 V VS1838B #CommonPartsLibrary #Sensor #Transducer #Optical-Sensor #Photo-Detectors #Remote-Receiver #TSOP38238
