TSOP1138SK1

VISHAY TSOP11..SK1 Vishay Semiconductors IR Receiver Modules for Remote Control Systems Description The TSOP11..SK1 - 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 operation with short burst transmission codes and high data rates. 13 646 Features Photo detector and preamplifier in one package Internal filter for PCM frequency Improved shielding against electrical field disturbance TTL and CMOS compatibility Output active low Low power consumption High immunity against ambient light Parts Table Part TSOP1130SK1 TSOP1133SK1 TSOP1136SK1 TSOP1137SK1 TSOP1138SK1 TSOP1140SK1 TSOP1156SK1 Carrier Frequency 30 kHz 33 kHz 36 kHz 36.7 kHz 38 kHz 40 kHz 56 kHz Special Features Enhanced data rate up to 4000 bit/s Operation with short bursts possible (≥ 6 cycles/burst) Block Diagram Application Circuit 2 25 kΩ Input PIN AGC Band Pass Demodulator VS 16842 3 OUT Circuit Transmitter TSOPxxxx with TSALxxxx R1 = 100 Ω VS C1 = 4.7 µF VO +VS 1 Control Circuit GND OUT GND µC GND R1 + C1 recommended to suppress power supply disturbances. The output voltage should not be hold continuously at a voltage below VO = 3.3 V by the external circuit.
