‧ High protection ability against EMI
‧ Circular lens for improved reception characteristics
‧ Available for various carrier frequencies
‧ Min burst length: 6 cycles
‧ Min gap length: 10 cycles
‧ Suitable for continuous code
‧ Low operating voltage and low power consumption
‧ High immunity against ambient light
‧ Long reception range
‧ High sensitivity
‧ Pb free and RoHS compliant
The IRM-37xxM series devices are miniature type
infrared receivers which have been developed and
designed by using the latest IC technology, specially
optimized to suppress interferences from TFT
backlight.
The photo diode and preamplifier are assembled
onto a lead frame and molded into an epoxy package
which operates as an IR filter.
The demodulated output signal can directly be
decoded by a microprocessor.
