TLV333: Low-Side Current Shunt Op-Amp Circuit to Single-Ended ADC for Cost-Optimized Monitor

oben enes sucu
Intellectual 285 points
Part Number: TLV333

Hello All,

I am looking for; https://www.ti.com/lit/an/sbaa353a/sbaa353a.pdf?ts=1712035145515&ref_url=https%253A%252F%252Fwww.google.com%252F

Low-Side Current Shunt Op-Amp Circuit to Single-Ended ADC for Cost-Optimized Monitor curcuit as shown;

This curcit is excatly what I need, but I have an one problem here, I want to make my voltage supply of LOAD +24V not +15V..

Is this curcuit okay for +24V load or am I need to look another TLV zero-drift type amplifier?

And if you have more suggestion about Current Shunt Monitoring please sahre with me.

Regards

    For as long as the Rsh is referenced to the ground, the circuit will be configured for the low-side current measurement where Vcm =~Ish*Rsh.  Thus, for as long as the 0< Vcm <10.6mV (Ish<10.6A), the circuit will work properly.  Therefore, it does NOT matter what supply voltage you use to bias the LOAD.
