Vishay Semiconductors
IR Receiver Modules for Remote Control Systems
Description
The TSOP17..KA1 - 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. TSOP17..KA1 is the
standard IR remote control receiver series, support-
ing all major transmission codes.
