ADT2689FXX

General Description

The ADT2689FXX is high quality low current receiver IC for infrared

remote control system.

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

Especially, It can be high performance for short burst & pause time

codes of LCD TV , IP TV, IP Set-top and etc. applications.

It has better distance performance in external light source environment

and LCD TV application.

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 circuits such as a high gain initial amplifier,

a gain control amplifier, a limiter, a double band pass filter,

a detection circuit, two comparator circuits, gain control circuit,

integrator circuit, a waveform shaping circuit assembled on a single chip.

Features

• Low current consumption ( Typ. 350uA@3V , 400uA@5V )

• Maximum interference safety against VCC noise & external light noise

• Optimization in short burst & short pause time application

( IP TV, IP set-top, Toy etc. )

• Min burst length : 6 and acceptable continuous code

• Output active low

* This specifications are subject to be changed without notice
