IR Receiver Modules for Remote Control Systems

LINKS TO ADDITIONAL RESOURCES

DESCRIPTION

These products are miniaturized receivers for infrared

remote control systems. A PIN diode and a preamplifier are

assembled on a lead frame, the epoxy package contains an

IR filter. The demodulated output signal can be directly

connected to a microprocessor for decoding.

The TSOP323.., TSOP343..series devices are optimized to

suppress almost all spurious pulses from energy saving

lamps like CFLs. AGC3 may also suppress some data

signals if continuously transmitted.

The TSOP321.., TSOP341.. series are provided primarily for

compatibility with old AGC1 designs. New designs should

prefer the TSOP323.., TSOP343.. series containing the

newer AGC3. The TSOP325.., TSOP345.. series contain a

very robust AGC5. This series should only be used for

critically noisy environments.

These components have not been qualified according to

automotive specifications.

FEATURES

• Very low supply current

• Photo detector and preamplifier in one package

• Internal filter for PCM frequency

• Improved shielding against EMI

• Supply voltage: 2.5 V to 5.5 V

• Improved immunity against ambient light

• Insensitive to supply voltage ripple and noise

• Material categorization:
