Such as attachment circuit ,0-3mV differential signal 301 times magnification, direct-drive differential ADC, this approach feasible? This circuit there is a need to modify the place? (Taking into account the product's power consumption and cost)
Conceptually, I don't see any problems, but keep in mind that for a 24 bit ADC, an LSB is only 0.2 uV. In the real world,
every solder connection will form a thermocouple which can be as much as 30 uV/deg C. PC board layout will be very important
to match all of the lengths, for example, from R104 to pin 5 and R105 to pin 3 should be identical lengths. For low noise,
you want to reduce the R106, R107 and R108 values, but if you reduce them too much, The ADA4051 can't drive the load.
Cut the values in half for a start. I would also reduce R104 and R105 and increase C100, C101 and C103 to maintain the poles
where you want them. If you can run the bridge on a higher voltage, that will give you more signal, but then you have to worry
Not an easy design, so it's time to build something and take some measurements!
