1 / 7 page VISHAY TSOP17..KA1 Document Number 82033 Rev. 10, 15-Oct-2002 Vishay Semiconductors www.vishay.com 1 12797 IR Receiver Modules for Remote Control Systems Description The TSOP17..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. TSOP17..KA1 is the standard IR remote control receiver series, support- ing all major transmission codes. Features • Photo detector and preamplifier in one package • Internal filter for PCM frequency • Improved shielding against electrical field distur- bance • TTL and CMOS compatibility • Output active low • Low power consumption Special Features • Continuous data transmission possible (up to 2400 bps) • Suitable burst length ≥ 10 cycles/burst Block Diagram Parts Table Application Circuit 25 kΩ 2 3 1 VS OUT Demo- GND Pass AGC Input PIN Band dulator Control Circuit Part Carrier Frequency TSOP1730KA1 30 kHz TSOP1733KA1 33 kHz TSOP1736KA1 36 kHz TSOP1737KA1 36.7 kHz TSOP1738KA1 38 kHz TSOP1740KA1 40 kHz TSOP1756KA1 56 kHz C1 = 4.7 µF TSOPxxxx OUT GND µC R1 =100 Ω +VS GND Transmitter with TSALxxxx VS R1 +C1 recommended to suppress power supply disturbances. VO The output voltage should not be hold continuously at a voltage below VO = 3.3 V by the external circuit. |
