Dear all

about the TPIC74100 Modulator frequency calculation ?

 1. How to calculator? 

     The equation for the modulation frequency is as follows: f (mod) (Hz) = (–2.2 × R mod ) + 54.5 kHz, when R mod = 8 kΩ to 16 kΩ (Datasheet)

      Rmod(12k) = F(mod) 28K but Rmod(24k) = ?why differnet result?

    why differnet result? (F(mod) )

 

 2.  F (mod) from the formula R (mode) and can calculate the value?

 

3.  detailed data on the modulation?

thanks.
