IR Receiver Modules for Remote Control Systems

Description

The TSOP12..WI1 - 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. TSOP12..WI1 is the

standard IR remote control receiver series, support-

ing all major transmission codes.

Features

• Photo detector and preamplifier in one

package

• Internal filter for PCM frequency

• Improved shielding against electrical

field disturbance

• TTL and CMOS compatibility

• Output active low

• Low power consumption

Special Features

• Improved immunity against ambient light

• Suitable burst length

≥ 10 cycles/burst
