hey guys
a very simple question;
i am waiting for my arduino MEGA to arrive in a few days.
i need to switch a bunch of LM1876's op amps on/off. they have mute pins that mute the signals passing through by receiving 5v!
so i figured i could use the arduino pins to switch the array of amps on/off.
however, my question is - do i need to put some kind of resistors inbetween or something to avoid drawing too much power/frying my arduino while muting 10+ LM1876's??
i should add, by default ALL AMPS WOULD BE MUTED AT THE SAME TIME - meaning id continuously be sending 5v through at least 10+ pins most of the time.
datasheet for the LM1876 can be found here :: http://www.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=snas097b&fileType=pdf
any thoughts would be greatly appreciated!
thanks,
