Description

The GL3276A is a bipolar analog ICs specifically developed for use in infrared remote control system receiving preamplifiers. 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.
