TSOP34838 Vishay Infrared Receivers 2.7-5.5V 38kHz IR Receiver Modules for Remote Control Systems

 TSOP34838 Vishay Infrared Receivers 2.7-5.5V 38kHz IR Receiver Modules for Remote Control Systems

1.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

2.DESCRIPTION
The TSOP322.., TSOP348.., TSOP324.. and TSOP344..series are miniaturized IR receiver modules for infraredremote control systems. A PIN diode and a preamplifier areassembled on lead frame, the epoxy package contains an IRfilter.
The demodulated output signal can be directly connected toa microprocessor for decoding.
The TSOP324.., TSOP344.. series devices are optimizedto suppress almost all spurious pulses from energy savinglamps like CFLs. The AGC4 used in the TSOP324..,TSOP344.. may suppress some data signals. TheTSOP322.., TSOP348.. series are provided primarily forcompatibility with old AGC2 designs. New designs shouldprefer the TSOP324.., TSOP344.. series containing thenewer AGC4.
