Vishay Semiconductors IR Receiver Modules for Remote Control Systems 22531-1 DESIGN SUPPORT TOOLS click logo to get started Models Available ORDERING CODE Taping: TSOP37...TT1 - top view taped TSOP37...TT2 - top view taped FEATURES • Very low supply current • Photo detectors 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 please see www.vishay.com/doc?99912 DESCRIPTION The TSOP37... series are miniaturized SMD IR receiver modules for infrared remote control systems. A PIN diode and a preamplifier are assembled on a PCB, the epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding. The TSOP374.. series devices are optimized to suppress almost all spurious pulses from energy saving lamps like CFLs. The AGC4 used in the TSOP374.. may suppress some data signals. The TSOP372.. series are provided primarily for compatibility with old AGC2 designs. New designs should prefer the TSOP374.. series containing the newer AGC4. These components have not been qualified according to automotive specifications.
