TSOP 1738 IR Receiver
EGP 6
See other suppliers →Description
A TSOP1738 is an IR receiver sensor that is used to receive an output signal from the IR based remote like a TV remote, AC remote, etc. It works on a frequency of 38Khz. It includes a photodetector and preamplifier inside it. It is a low power device that is highly immune to ambient light. When you press any button on an IR remote, the IR remote sends a signal associated with that button at 38KHZ. That is then received by the photodetector inside the sensor and the pre-amplified using a preamplifier. The pre-amplified signal can be further used by the microcontroller to decode the received data from the sensor. 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 Low power consumption High immunity against ambient light Continuous data transmission possible (up to 2400 bps) Suitable burst length ≥10 cycles/burst Absolute Maximum Ratings : Basic Characteristics : Application Circuit : TSOP-1738 Applications Receive IR signals Decode Remote signals Analyse, re-create or duplicate remote Signals Wireless control applications Receiver circuit for IR remote controls IR Remote tester circuits
