Tool/software:
Hello, everyone.
The principle diagram is as follows, the chip output positive voltage is 14.9V, but the negative voltage is only -14.3V, how can the negative voltage improve the accuracy?
Thanks,
Ivy

Hi Ivy,
Could you share why you need accurate negative voltage in your system?
And you can see this document to improve the circuit. https://www.ti.com/lit/an/slvafu0/slvafu0.pdf
