(Note 1) : The capture range is represented by the value in 19kHz equivalent.
(Note 2) : The low-pass filter used to measure electrical characteristics must have 19kHz attenuation of –90dB or more
negative value of dB and 38kHz attenuation of –70dB or more negative value of dB.
(Note 3) : Be carefull that the combination of pin 22 ⊕ and the others causes dielectric breakdown easily.
