IR Receiver Modules for Remote Control Systems
DescriptionThe TSOP22..YA1 - series are miniaturized receivers
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. TSOP22..YA1 is the
standard IR remote control receiver series, support-
ing all major transmission codes.
Features Photo detector and preamplifier in one package Internal filter for PCM frequency Improved shielding against electrical field distur-
bance TTL and CMOS compatibility Output active low Low power consumption
Special Features Improved immunity against ambient light Suitable burst length ≥ 10 cycles/burst
