IR Receiver Modules for Remote Control Systems

DESCRIPTION

The TSOP322.., TSOP348.., TSOP324.. and TSOP344..

series are miniaturized IR receiver modules for infrared

remote control systems. A PIN diode and a preamplifier are

assembled on lead frame, the epoxy package contains an IR

filter.

The demodulated output signal can be directly connected to

a microprocessor for decoding.

The TSOP324.., TSOP344.. series devices are optimized

to suppress almost all spurious pulses from energy saving

lamps like CFLs. The AGC4 used in the TSOP324..,

TSOP344..

may

suppress

some

data

signals.

The

TSOP322.., TSOP348.. series are provided primarily for

compatibility with old AGC2 designs. New designs should

prefer the TSOP324.., TSOP344.. series containing the

newer AGC4.

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

• Supply voltage: 2.5 V to 5.5 V

• Improved immunity against ambient light

• Insensitive to supply voltage ripple and noise

• Material categorization:
