I need to design a load cell circuit that gives me a programmable gain and a resolution greater than 16-bits with an output rate > 100sps. My load cell gives me 3.29mV/V and the excitation voltage is 10V.
There are plenty of IC's from Analogue Devices (AD7730) but there is always a tradeoff between resolution, output rate, etc. I have found a device that does this all in one but the excitation voltage is 5V when I want to use 10V. Using 5V excitation then gives me even less signal to work with so I need the best trade off.
There must be a way to have my cake and eat it, I am new to load cells so my knowledge in this is very limited.
