#153196 - Load cell shield |
I built a load cell board with LCD based on the AD7730 DIP package and I got satisfying results from first board using anlog and digital solid ground planes meeting in one point under the AD7730, with some minor drift proplems.
Where do you connect the shield? do you leave it open or do you connect it to both analog inputs with balancing resistors? Mahmood |
