Hello,
I am very new to integrated circuits! I am trying to understand the data sheet but most of it is beyond my comprehension... could anyone lend some help?
I am looking at the datasheet for the LM2907/LM2917 frequency to voltage converters specifically figure 7 the speed switch.
My questions are as follows:
1) Can I control a relay as the load? I am assuming I need a LM2917 and apply additional current to the other side of the relay but I did not see anything in the circuit specifying anything other than the note above regarding zener regulated options. It says 6-24Vcc I am assuming that is generated voltage from the variable frequency or do I need to provide that somewhere?
2) Can I use a 10K linear potentiometer to adjust R and just use say two 1uF capacitors? I will use the two 5K resistors shown in diagram.
3) How do I induce "hysteresis" so that my circuit will not switch off and on quickly near threshold?
Thank you for your help!
