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.
