BL20106 is produced by Shanghai Belling Electronic Technology Co., Ltd. It is infrared remote control system for receiving bipolar preamplifier ASIC. Its features are: Low power consumption, low voltage, the internal band-pass filter everywhere; Output is an open collector output, and it can be connected with CMOS and TTL circuit; Input can be directly connected with the photodiode. Domestic and foreign similar products are D20106, CX20106, KA2184A and these can be directly interchangeable. The figure below shows a typical application circuit constituted by the BL20106, andthe circuit is very simple, and its typical operating voltageis 4.7 ~ 5.3V, the circuit operating frequency is F0 = 40kHz BL20106 shape pin map.
