Capable of accepting a photodiode directly, these ICs house a high gain initial amplifier, a limiter, a band-pass filter, a detection circuit and a waveform shaping circuit assembled on a single chip. Features • Less changes of malfunction associated with a high-frequency lighting fluorscent lamp internal trap circuit. • The central frequency can be varied with an external resistance: fo=30 to 80KHz fo rimming reduce central frequency variance. • Few external parts. Internal pull-up resistance and power filter resistance. Lower-capacitance external capacitor • Open collector output Open collector output with a pull-up resistance.
