Hello,
I'm currently working with an ADuC847 processor to read signals from a load cell, the signals are in the range of 0mV to 10mV. The problem is that i'm facing way too much noise on the reading, i've tried a lot of things, enable and disable CHOP, change the SF ISR, but my biggest problem is that i need a great aquisition frequency and not too much noise.
I'm reading the ADC section on the Datasheet but i simply can't find out a solution. Is there any digital filters that work fine? I'm trying to implement some, but none is working and the weigh variation is way too big (~10g). The only way to reduce the variation is to reduce the aquisition frequency, but i need a frequency of, at least, 7ms.
