Title: small analog signals
Post by: dutch_CAT on December 07, 2006, 05:37:22 PM

Hi,
is it possible to change the analog input range from the 0-5V to say 0-1 Volt?

I have an application where I need to read one analog value with a 0-1 V range

if the range is corresponding the 10 bit conversion would be fine, otherwise I need at least 13 bits to get enough resolution.

So if I can not change the analog reference voltage what would your suggestion be to get a higher resolution?

thanks and have a nice day

T100MD1616+ has two channels of 0-1V ADC.

You can't change the ADC resolution. The only way is to get better resolution is to get a I-7017 or I-7018 which has 16-bit resolution.
