INFRARED RECEIVER MODULE

Description

The OS-1638 is miniaturized infrared receivers for remote

control and other applications requiring improved ambient light

rejection.

The separate PIN diode and preamplifier IC are assembled on

a single leadframe.

The epoxy package contains a special IR filter.

This module has excellent performance even in disturbed

ambient light applications and provides protection against

uncontrolled output pulses.

Features

• Photo detector and preamplifier in one package .

• Internal filter for PCM frequency.

•

nner shield,good anti-interference ability.

• High immunity against ambient light.

• Improved shielding against electric field disturbance

• 3.0V or 5.0V supply voltage; low power consumption.

• TTL and CMOS compatibility.

• Suitable transmission code:NEC code,RC5 code.

Applications:

1. Optical switch

2. Light detecting protion of remote contol

• AV instruments such as Audio,TV,VCR,CD,MD,DVD,etc.

• Home appliances such as Air-conditioner,Fan,etc.

• CATV set top boxes

• Multi-media Equipment
