IR Receiver Modules for Remote Control Systems
Description
The TSOP22..WE1 - series are miniaturized receiv-
ers 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..WE1 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 disturbance
TTL and CMOS compatibility
Output active low
Low power consumption
Special Features
Improved immunity against ambient light
Suitable burst length ≥ 10 cycles/burst
