ADT2689SXX

General Description

The ADT2689SXX 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 is optimized for Sony 20bit code of LCD TV,

Set-top and etc. applications.

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 double band pass filter, a detection

circuit, two comparator circuits, gain control circuits, integrator

circuits, 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

• Acceptable Sony 20Bit codes for set-top or Toy application

• Min burst length : 10 and acceptable continuous code for max. 1.2ms

• Output active low

* This specifications are subject to be changed without notice
