I'm built a circuit board for my Analog card. My normal inputs will be 0-5
vdc but the max allowed on the ADC is 10 vdc.
I was thinking about putting some zeners across the input circuit so the
voltage will never go above 10 volts. I left a space from each input to
ground for a surface mount 1/2 watt resistor. These were there so we could
do a 4-20ma conversion.
So, First, will zeners work without affecting my normal input voltage?
Second, are zeners available close to the 10 volt range?
Any better simplier solutions?
Thanks,
Richard
