for a project I am using some DMS and an INA125P as an instrumentation amplifier. I am using the INA125P exactly as described in the data sheet with a reference Voltage of 2.5V. Now my main concern is, that I measure much noise, depending where I am. I am not using anything to block noise but I was thinking about a box made of metal. Is that a good idea and are there any other hints out there?
