VSOP58438

VISHAY  VSOP58438  信号调节器, 38 kHz, 2.7 V, 5.5 V, QFN, 8 引脚, -25 °C

The is a 38kHz Preamplifier designed for use in an IR receiver application together with a photo pin diode. It is a sophisticated receiver concept that is very sensitive to data signals and compatible with the most common data formats for IR remote control. On the other hand it is immune to DC current caused by DC light sources such as tungsten bulbs. The disturbance signal of fluorescent lamps is suppressed, there are no unwanted pulses at the output.
