ADT2520BXX

General Description

The ADT2520BXX is a miniaturized receiver IC for infrared remote

control system.

It has a wide voltage operating such as 2.7~5.5V, a high sensitivity.

Wide operating voltage is very suitable to the hand-held battery

operating systems, e.g., electrical toy.

It has 5 trimming cells for the fined adjust of center frequency.

These ICs are capable of accepting a photodiode directly and

include many excellent circuit such as 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.

Features

•Wide Operating Supply Voltage 2.7V ~ 5.5V

• Internal voltage reference circuit for wide operating built-in.

• No external components necessary.

• Suitable for minimum burst length of 6 pulses per burst.

• Continuous codes ( <1ms pause time ) are acceptable.

• Output active low.

• Carrier frequency 37.9/56 KHz available

* This specifications are subject to be changed without notice
