GL3276A GL3276A 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.
Pin configuration (SOP) • 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.
