TSOP34840UH1

The TSOP34840UH1 is designed as miniaturized receiver 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. It is the standard IR remote control receiver series for 3V supply voltage, supporting all major transmission codes.

TSOP34840UH1 has seven features. (1) Photo detector and preamplifier in one package. (2) Internal filter for PCM frequency. (3) Improved shielding against electrical field disturbance. (4) TTL and CMOS compatibility. (5) Output active low. (6) Supply voltage range would be from 2.7V to 5.5V. (7) Improved immunity against ambient light. That are all the main features.

Some TSOP34840UH1 absolute maximum ratings have been concluded into several points as follow. (1) Supply voltage would be from -0.3 to +6.0V. (2) Its supply current would be 3mA. (3) Its output voltage would be from -0.3 to VS + 0.3V. (4) Its output current would be 10mA. (5) Its junction temperature would be 100°C. (6) Its storage temperature range would be from -25 to +85°C. (7) Its operating temperature range would be from -25 to +85°C. (8) Its power consumption (Tamb 85 °C) would be 30mW. (9) Its soldering temperature t 5s would be 260°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics about TSOP34840UH1. (1) Its supply current would be min 0.7mA and typ 1.2mA and max 1.5mA at Ev=0. (2) Its supply voltage would be min 2.7V and max 5.5V. (3) Its transmission distance would be typ 35m. (4) Its output voltage low would be max 250mV. (5) Its minimum irradiance (30 to 40kHz) would be typ 0.2mW/m2 and max 0.4mW/m2. And so on.
