Preamplifier for Remote Control Signal Reception
Description The CXA1511L/M is a bipolar IC used for preamplifiers that receive signals in infrared remote control systems. These ICs consist of a first-stage amplifier, limiter amplifier, band-pass filter, band elimination filter, signal waveform detection circuit and waveform shaping circuit. Features Low power consumption (VCC = 5V, 9mW typ.) Low supply voltage (VCC = 5V) Filters (center frequency can be varied through external resistor: fo = 30kHz to 60kHz, 40kHz typ.) Elimination of inductors prevents magnetic field inductance interference. Optical reception diode can be coupled directly. Collector output (pull-up resistor, TTL and CMOS can be connected directly) Applications TVs, VCRs, audio equipment Structure Bipolar silicon monolithic IC Block Diagram and Pin Configuration 8 pin SIP (Plastic) 8 pin SOP (Plastic)
