1 / 8 page ![]() TSOP12..KA1 Vishay Telefunken 1 (8) Rev. 3, 30-Mar-01 www.vishay.com Document Number 82125 Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type fo Type fo TSOP1230KA1 30 kHz TSOP1233KA1 33 kHz TSOP1236KA1 36 kHz TSOP1237KA1 36.7 kHz TSOP1238KA1 38 kHz TSOP1240KA1 40 kHz TSOP1256KA1 56 kHz Description The TSOP12..KA1 – series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. 12797 Features D Photo detector and preamplifier in one package D Internal filter for PCM frequency D Improved shielding against electrical field disturbance D TTL and CMOS compatibility D Output active low D Low power consumption D Suitable burst length ≥10 cycles/burst Special Features D Enhanced immunity against all kinds of disturbance light D No occurrence of disturbance pulses at the output Block Diagram 94 8136 PIN Input AGC Control Circuit Band Pass Demodu- lator 80 k W 1 2 3 VS OUT GND |
