GL3276A

· 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.

The GL3276A is a bipolar analog ICs specifically developed for use in infrared remote control system receiving preamplifiers. Capable of accepting a photodiode directly, GL3276A 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.
