Dear TI engineers:
I would like to design a low-noise 50Hz notch filter. The first requirement is that its PSD noise should be sufficiently low: 1uV/rt(Hz) at 1Hz, 10nV/rt(Hz) at 10KHz. Then its power consumption should be less than or equal to 10mA.…
我根据仿真得到INA的两输入电压和Vref电压,然后输入下面 Analog engineer's calculator 计算工具,计算工具选择INA826型号,可以得到此输入共模电压下的输入和输出范围,如下截图,输出最大是5.452V,因此是输入共模电压限制了输入和输出范围:

建议您将Vref设置在供电电压中间值,或使用双电源供电,这样输入和输出范围广一些。建议您在上述链接下载 Analog engineer's calculator…

Part Number: ADS1231
Hello engineer. I am using TI's ADS1231 chip to design a strain acquisition development board, and the schematic diagram is shown nearby. I found a problem while using it on site. I used 5V voltage to excite it, and theoretically…
