Hi Pete el al,
In this topic:
We are using the INA326 device, to convert range (0V-5V) to (0V-3.3V). And in this version, we decided to ignore the non-linear region of output INA326.
And for preparing the next one, I want to update the schematic, so we can fully convert (0V-5V) to (0.1V-3.3V).
1. Solution 1: I use a LM111 device for creating the low reference voltage, please see the simulation attached file and help give me advice or suggest me a better device.
2. Solution 2: Can I supply the negave voltage for INA326 at V- pin, which means INA326 will be operated with +-5V, and the linear region of output will be widen. And the output will be linear in 0V-3.3V. Do you think this solution is okay for implement?
Thanks and Best Regards,
