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. ? 8ms data pause time codes are acceptable . ● 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 ?
