Q3> The measured current was tested in the Current Shunt Amplifer ( INA198 ).
However, when the load is changed to 5V, the output voltage of the INA198 read by the ADC is not linearity.
Small current value due to fluctuation in 100…
Hi,
Where Can I find an explanation for the software?
The buck_nonpowerSUITE project is for F28004X. What all the changes needed to port it to F28379D?
Instead of U2-OPA353 for current sensing, Can I directly use some current sense amplifiers? like INA293…

Q5> In the previous post, this is the (maximum) current sense value in the [Firgure1] Block Diagram.
+5V_INT : (normal) 1.5A (max)) 3A
+5V_EXT : (nomal) 0.7A (max) 1.5A
Please give me advice and help on what to change or modify…
Dear Sir,
please have a look at schematics PMP30168 page 2 , voltage across shunt resistor R301 1milliOhm drives high side amplifier U301 INA198; by gain x100 your current monitor output signal is 1V/10A. You could either do a peak detection, or by adding…
Hi Patrick,
Customer changed solution to INA198 and below is his new circuit. I thought the circuit is OK, could you please provide me your advice?
Thanks very much.

Part Number: INA196 Other Parts Discussed in Thread: TINA-TI , INA193 , INA198 , INA194 , INA195 , INA197 Hello,
I'm using INA196 to measure current flowing through the load as per attached picture. I have wide range of currents, so I use INA196 to measure…
Hello Alfred,
Thanks for reaching out on the forum. There are a few items to consider with the schematic you posted.
The first would be to add a bypass capacitor on the supply pin if there is not one already on the portion of the schematic not shown…
Hideyuki-san,
I have not been able to find distribution data that you requested on this part for Vsense > 20mV or < 20mV as this part is quite old. Also, when Vsense < 20mV, the device’s error is not constant anymore and thus characterizing total error…
