i'm looking for a 2 7-segment dc voltage monitor . Any one has any ideas

 

I have moved this question into it's own thread, since "hijacking" the other thread is impolite.

What range of voltage do you need to measure?

 

if you wish to use a single chip, i would suggest ICL7106 which can drive a non-multiplexed LCD or the ICL7107 which will directly drive a common anode LED display.

as thingmaker3 has asked, what's your voltage range?

i need it to measure between 4.5 and 5.5 volts...no more ..no less.
thanks

 

Does it have to be 2 digits, or will 3.5 be acceptable?
