Smallest IR Receiver

  1. Looking for whatever is the smallest integrated IR receiver for r/c at
    38kHz.
    Problem is that even the Sharp GP1U series is too big.
    I'm looking for something the size of a 5mm LED.
    Does anything like this exist?

    Sure do

    IR receiver for R/C? you mean IR/C?

    Check this out

    940nm infrared receiver. The center carrier frequency is 38kHz. It can
    see horizontally and vertically at a 45 degree angle. 5Vdc-TTL and
    CMOS compatible. Low power consumption-1.2 to 5mA. Photo detector and
    preamplifier in one package. Improved immunity against ambient light.
    Complete Specs at www.bgmicro.com. LED1130.....

    These are turning up in several electronics surplus outlets.

  4. Looks identiucal to the Vishay parts ( e.g. tsop34837)
    Vishay also do a SMD variant, TSOP36237, whch is smaller in some dimensions, but not much.

    The Vishay parts work very well....

  6. The GP1u series has long been obsolete so don't design it in. The
    replacement is the same as the American opto device above. I wouldn't use
    this- noise immunity. The metal can version is much better. I can't tell you
    what the sharp part number is. The supplier in the UK puts their own number
    in their catalogue- HMV602 ( H or V). It works very well. package size is
    about 7mm sq. x 3mm.
    I don't think you'll get an integrated IR detector the size of a 5mm
    led.....
     
  7. Thanks for the help guys.

    As others have pointed out, the modern IR receivers are all marginally
    wider and higher than a 5mm led, but not by very much. Overall the
    space requirements for a 5mm led and a IR reciever is about the same
    in practical terms.

    In addition to the American Micro products there are numerous asian
    made items such as the Brightled BRM1030
