IR Receiver Modules for Remote Control Systems
Description
The TSOP48.. - 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
1
decoded by a microprocessor. TSOP48.. is the stan-

3
dard IR remote control receiver series, supporting all
16672
major transmission codes.
Features
• Photo detector and preamplifier in one
package
• Internal filter for PCM frequency
e3
• Improved shielding against electrical
field
disturbance
• TTL and CMOS compatibility
• Output active low
• Low power consumption
