Hi,

Can any one suggest me a circuit to measure differential voltage from 0 Volts to 3500 milli Volts (3.5 Volts) similar to the feature available in multi meters to measure milli volts.

Thanking You,
Ravi

Hi,

in a (cheap) multimter there often is a ICL7106/ICL7107 chip.
It is for 3 1/2 digit display and often is configured for a +/- 200mV range. With two external resistors you can adjust range to your 3500mV.
