Infrared IR Receiver Sensor For PCM Remote Control System

Description:

The LFN – 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. TSOP1238 is the
standard IR remote control receiver series, supporting
all major transmission codes. 

Features:

Photo detector and preamplifier in one package

Internal filter for PCM frequency

TTL and CMOS compatibility

Output active low

Improved shielding against electrical field 
disturbance
Suitable burst length ≥10 cycles/burst

Low power consumption

High immunity against ambient light

Continuous data transmission possible (800 bit/s)
