Part Number: AMC3330-Q1
Other Parts Discussed in Thread: TIDA-010232, OPA320, TLV6001

Dears,

请帮忙看下如下问题,多谢!

1.请问这个两个PE怎么连接的

2.文档说是  6001 精度 需要提高? 因为失调?

3.如下这句话能否帮忙具体解释一下,多谢!

  • 您好,

    1、在下面 TIDA-010232 产品首页 Design files处有其完整的设计资料,连接方法您可以查看其中提供的原理图,如下截图所示设计资料:

    2、您是指下面截图这里的描述吗?如果是的话,它的意思是如果需要更高的精度,可以使用更高精度的放大器,比如将TLV6001换为OPA320,看括号里备注,这里主要考虑OPA320失调电压比TLV6001小的多。

    3、

    您可以看对应的英文描述: These additional resistors must have a separate connection to PE。就是通过分开的或不同的支路连接。
