I’m using a variety of load cells, the highest output is ~3mV/V and I’d like to use an excitation of 10V. thus the output range of the loadcell will be -30mV to 30mV. Any ideas how to boost that voltage swing to a -5 to 5 range with minimal noise?
I’m currently using an INA333 and successfully boosting the signal to 0 to 5V but due to noise in the signal I want to utilize the full -5 to 5.
I’m currently suffering from +/-7.2mV of jitter on the output of the current setup, changing the gain didn’t change the amount of jitter so in theory if I can double the useful range of the signal while keeping the jitter at 7mV the noise will effectively be halved.
Which Instrumentation Amplifier is up to this task?
