请教一下,因我开发的产品的需要,我想用1.8V的LDO给INA333供电,查看INA333的datasheet,此芯片的输入电压范围为>1.8V,但LDO的输出电压约在1.795左右,请问题,如果用此

在有220V的交流电线路上,并上施加一个5V的隔离直流电压(该电压与220V不共地),5V经过一个限流电阻产生一个电流,能否用INA826去检测改电流大小,220V交

使用INA148放大一个3-4V左右的电压,使用正负5V供电测量结果十分准确,但只使用正5V时,会有一定的误差,这是什么问题?我看datasheet上16页的8.2.3 Single-Supply Differential Amplifier,是可以那么用的啊?
