1 / 7 page VISHAY TSOP348..RF1 Document Number 82237 Rev. 1, 16-Jun-03 Vishay Semiconductors www.vishay.com 1 16666 2 1 3 IR Receiver Modules for Remote Control Systems Description The TSOP348..RF1 - series are miniaturized receiv- ers 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. TSOP348..RF1 is the standard 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 = GND, 3 = VS Parts Table Block Diagram Application Circuit Part Carrier Frequency TSOP34830RF1 30 kHz TSOP34833RF1 33 kHz TSOP34836RF1 36 kHz TSOP34837RF1 36.7 kHz TSOP34838RF1 38 kHz TSOP34840RF1 40 kHz TSOP34856RF1 56 kHz 30 kΩ 2 3 1 VS OUT Demo- GND Pass AGC Input PIN Band dulator Control Circuit 16833 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 = 2.0 V by the external circuit. 17170 |
