Tool/software:
I would like to know the MAX V+ current consumption of INA21X. Is that suitable using one 100mA LDO as the power source for 30 x INA21X ?
Hello,
The Quiescent current can be found in the datasheet in the electrical characteristics table. There is a section labeled "Power Supply" that details the maximum quiescent current draw of the device:
In addition to this, the device will need to supply current to whatever external circuitry you are using to read the voltage output, but this will be far below 100mA. The LDO you suggested will be able to supply more than enough power for this device.
Let me know if you have any more questions,
