i want to use AD620 as a pre-amplifier for a thermopile sensor. thermopile sensor impedance is 60Kohm. so for the ground return connection, should i just treat that thermopile as a thermocouple and connect pin3 input+ to reference and ground? or i have to connect pin3 input+ to reference and ground with a 100Kohm resistor?
