Description
The TSOP12..XG1 鈥?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 de-
coded by a microprocessor. The main benefit is the
reliable function even in disturbed ambient and the
protection against uncontrolled output pulses.
