   [re] 로드셀 증폭에 관해서 여쭈어볼것이 있습니다
.
.
ad620/www.anlog.com 에서
page15/20은 single5v이지만 ...ic가 하나더있으니까..귀찮아도양전원으로..
제가 썼던것은 apm01이나 ad620도 아래와같이..
.
도면 43로 하시면 틀림없읍니다.도면그대로..+-양전원입니다.
.
1.로드셀의출력회로/내부회로는 브릿지로 되어있습니다.
   full부하일때 1/2mv나오니까 증폭율1,000으로 하십시요.그럼1/2v나오지요..
   로드셀/브릿지의 위아래는  +10v 를 걸어야합니다.
   +9v등 낮게는 걸어도+12/15v등 높게는 안돼..databook이 +10v때일겁니다..
   옆으로의 출력신호2개/+in/-in으로 ad620의 차동입력이됩니다.
.amp01의 회로를 참고...

2.ref=접지 -vs=-12v -in은 로드셀.로 연결하십시요.
