The TSOP9 series of infrared receivers for remote control applications from Vishay Intertechnology delivers improved dark-ambient and disturbed-ambient sensitivity to infrared signals, better suppression of RF noise, and excellent pulse-width accuracy. They provide increased robustness against disturbances such as IR emissions from CFL lamps and RF emissions from on-board Wi-Fi antennas. The improved pulse width accuracy allows lower bit error rates for almost any code. The IR receivers are insensitive to supply voltage variations and ripple noise. The TSOP9 series receivers are available in three packages, mold, minimold, and minicast and modulation frequencies of 30 kHz, 33 kHz, 36 kHz, 38 kHz, 40 kHz, and 56 kHz.
