Other Parts Discussed in Thread: TIDA-00313, INA226
I want to make a circuit that can measure voltage between -18v to 0v using ina229, i have check TIDA-00313 design and make some modifications, blow is my Schematic diagram.
which use a inverter Charge pump to generate negative 19v rail, the ina229 ic get it power form -19v rail and the zener diode.
To communicate with SPI to MCU i use a digital isolator ADUM1411ARWZ
Please help me to check whether the following circuit can work or not, thank you!
