OS-0038K-K INFRARED RECEIVER MODULE Description The OS-0038K-K 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. • Inner 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 Absolute Maximum Ratings Parameter Symbol Ratings Unit Notice V 2.7-5.5 V — Operating Temperature Topr - ~+65 — Storage Temperature Tstg -40~+85 — Soldering Temperature Ts 260 4mm from mold body less than 5 sec Supply Voltage Distributed by Conrad Electronic SE, Hirschau, Germany OS-0038K-K Electrical And Optical Characteristics Parameter Ratings Symbol Min.
