Description
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 (V
• Low supply voltage (V
• Filters (center frequency can be varied through
• Elimination of inductors prevents magnetic field
• Optical reception diode can be coupled directly.
• Collector output (pull-up resistor, TTL and CMOS
