PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be de- coded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. 16 078 Features D Photo detector and preamplifier in one package D Internal filter for PCM frequency D TTL and CMOS compatibility D Output active low D Improved shielding against electrical field distur- bance D Suitable burst length ≥6 cycles/burst Special Features D Small size package D Enhanced immunity against all kinds of distur- bance light D No occurrence of disturbance pulses at the out- put D Short settling time after power on (<200ms) Block Diagram 9612226 PIN Input AGC Control Circuit Band Pass Demodu- lator 30 k W 2 3 1 VS OUT GND |
