in front of an ADC circuit i have a 4051 multiplexer.i try to measure the output of 8 thermocouples.
now my question ;
instead of using 8 thermocouple amplifiers before the 4051 - can i use 1 amplifier between 4051 and ADC and connect the thermocouples directly to 4051 inputs ?
(i want to ask if the 4051 disturb the millivolt range outputs of thermocouples ?)
