FEATURES

• Low supply current

• Photo detector and preamplifier in one package

• Internal filter for PCM frequency

• Improved shielding against EMI

• Supply voltage: 2.7 V to 5.5 V

• Improved immunity against ambient light

• Insensitive to supply voltage ripple and noise

• Component in accordance to RoHS 2002/95/EC and

WEEE 2002/96/EC

DESCRIPTION

The TSOP21.. series are miniaturized receivers for infrared

remote control systems. A PIN diode and a preamplifier are

assembled on a lead frame, the epoxy package acts as an IR

filter.

The demodulated output signal can directly be decoded by a

microprocessor. The main benefit of the TSOP21.. is the

compatibility to all IR remote control data formats.

This component has not been qualified according to

automotive specifications.

OUT

The external components R1 and C1 are optional

to improve the robustnes against electrical overstress

(typical values are R1 = 100

Ω, C1 = 0.1 µF).

The output voltage V

below 1 V by the external circuit.

The capacitive load at the output should be less than 2 nF.
