HS0038A2.
Vishay Telefunken
Photo Modules for PCM Remote Control Systems
Description
The HS0038A2. – 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. HS0038A2. is the
standard IR remote control receiver series, supporting
all major transmission codes.
