TSOP322.. Document Number 82228 Rev. 1.2, 31-Jan-05 Vishay Semiconductors www.vishay.com 1 16672 1 2 3 IR Receiver Modules for Remote Control Systems Description The TSOP322.. - 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. TSOP322.. is the stan- dard IR remote control receiver series for 3 V supply voltage, supporting all major transmission codes. 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 • Supply voltage: 2.7 V to 5.5 V • Improved immunity against ambient light Mechanical Data Pinning: 1 = OUT, 2 = VS, 3 = GND Parts Table Block Diagram Application Circuit Part Carrier Frequency TSOP32230 30 kHz TSOP32233 33 kHz TSOP32236 36 kHz TSOP32237 36.7 kHz TSOP32238 38 kHz TSOP32240 40 kHz TSOP32256 56 kHz 30 k Ω 2 3 1 VS OUT Demo- GND Pass AGC Input PIN Band dulator Control Circuit 16835 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 voltageshould not be hold continuously at a voltage below VO = 2.0V by theexternal circuit. 17170 e3 |
