1 / 8 page TSOP348..SJ1 Document Number 82265 Rev. 1.1, 28-Feb-05 Vishay Semiconductors www.vishay.com 1 16656 1 2 3 IR Receiver Modules for Remote Control Systems Description The TSOP348..SJ1 - 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..SJ1 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 TSOP34830SJ1 30 kHz TSOP34833SJ1 33 kHz TSOP34836SJ1 36 kHz TSOP34837SJ1 36.7 kHz TSOP34838SJ1 38 kHz TSOP34840SJ1 40 kHz TSOP34856SJ1 56 kHz 30 k Ω 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.
