IR Receiver Modules for Remote Control Systems

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 TSOP383.. 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

TSOP381..

series

are

provided

primarily

for

compatibility with old AGC1 designs. New designs should

prefer the TSOP383.. series containing the newer AGC3.

The TSOP385.. 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

• Supply voltage: 2.5 V to 5.5 V

• Improved immunity against ambient light

• Insensitive to supply voltage ripple and noise

• Material categorization:

for

definitions

of

compliance
