Part Number: INA226 Other Parts Discussed in Thread: TIDA-00313 , INA186 , INA193 , Can I use INA186 or INA193 according to the topology of TIDA-00313 –48-V Telecom Current, Voltage, and Power Sense With Isolation Reference Design?
We don't need an…
Hi Allan,
The differential voltage between -57 and +57 volts exceeds the 85V limit of both the INA237 and INA740B. Unfortunately we do not offer digital current sensors that accept common mode voltages above 85V. We do offer 120Vcm devices, but they are…
Hello Bella,
Yes, here is a reference design that shows how to use the INA226 at -48V: https://www.ti.com/tool/TIDA-00313
When adapting this to your design with the INA228, you can adjust to the negative voltage you need, and just be sure that the digital…
Hi Boris,
A bidirectional device refers to the current being bidirectional, not the common mode voltage. However, if you would like to apply a negative input voltage you could follow this reference design which allows for a negative range of voltages…
Part Number: TIDA-00313 Other Parts Discussed in Thread: INA226 After studying the TIDA-00313 schematic and filling in the blanks of how a -48V supply would be connected, it appears to me that the VBUS voltage divider current is going through the shunt…
Part Number: INA229 Other Parts Discussed in Thread: TIDA-00313 , INA226
Hi,
I want to make a circuit that can measure voltage between -18v to 0v using ina229, i have check TIDA-00313 design and make s ome modifications, blow is my Schematic diagram.

Part Number: INA226 Other Parts Discussed in Thread: TIDA-00313 Hi,
I want to use the ina226 chip to measure the current and voltage of a voltage source that varies from -1.5V to -3V.
The digital part (I2C microcontroller) is supplied with a voltage of…
Hello Corrado,
Thank you for using the TI forum. You could use the INA228 with negative VCM if you use isolation, similar to what is done in this reference design: https://www.ti.com/tool/TIDA-00313
Just make sure all the logic levels work with whichever…
Part Number: INA238 Other Parts Discussed in Thread: TIDA-00313 , LMR33620
Hi Sir,
My customer would like to use the INA238 to monitor the multi-channel voltage and refer to the TIDA-00313 schematics, could you please help to review the schematics?
The…
Part Number: INA226 Other Parts Discussed in Thread: TIDA-00313 , Hi team, We have designed an isolated voltage monitoring system as per TIDA-00313. Below I add a few doubts about this. 1)Do we require to connect +volt external power supply for INA226 Vs…
