STANDARD APPLICATIONS (AGC2/AGC8)
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
DESCRIPTION
The TSOP48.. 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 TSOP48.. is the standard IR remote
control receiver series, supporting all major data formats.
This component has not been qualified according to
automotive specifications.
