CXA1511L/M
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.
