HL3280
PREAMPLIFIER FOR REMOTE CONTROL USE
1. OVERVIEW
1.1 Description
The HL3280 is a miniaturized receiver IC for use in the infrared remote control system.
It has a wide voltage operating such as 2.7~5.5V, a high sensitivity, and good noise
immunity. Wide operating is very suitable to the hand-held battery operating systems,
such as electrical toy.
This can also be suitable for high optical and electrical disturbances.
It has the frequency selecting Pads for setting the center frequency of band-pass filter
and also has 5 trimming Pads for the fine adjustment of center frequency.
The HL3280 is capable of accepting a photodiode directly and include many excellent
circuit such as an internal voltage reference for wide voltage operating, a high gain initial
amplifier, a gain control amplifier, a limiter, a band pass filter, a detection circuit, two
comparator circuits, gain control circuits, integrator circuits, a waveform shaping circuit
assembled on a single chip.
1.2 Features
• Wide operating supply voltage 2.7V ~ 5.5 V
• Built-in internal voltage reference circuit for wide operating
• Maximum interference safety against optical and electrical disturbances
• No external components necessary
• The center frequency can be varied with option PADs
( 32.7kHz, 36.7kHz, 37.9kHz, 40kHz, 56.7kHz)
• Internal filter for a high frequency lighting fluorescent lamp
• Open collector output (Open collector output with a pull-up resistor)
• Output active low
