Part Number: INA253-Q1 Tool/software:
For our HW design, we ’ d like to use INA253A3-Q1 for current sensing feedback on dither valve control. And for this current sensing circuit block, ASIL C is needed.
After FMEDA calculation based on HW,…
Part Number: INA253-Q1 Other Parts Discussed in Thread: INA253EVM Hello,
there are some problems with INA253-Q1 (100 mV/A module): i linked the 5 V power supply to VS and GND connectors, the current generator is linked to through a breadboard and a resistance…

HI Venkata,
1) In general, using the INA851 with 0.1% tolerance resistors with 20ppm/C drift will offer very good performance.
Using the root sum of the squares, we can add uncorrelated errors to obtain an estimate of error. For example, the INA851 datasheet…
Part Number: INA253 I am measuring about 15 mv Peak to Peak of noise in the 50 Khz region on the output. This seems to be in the chips spec. However it is being used as a feedback signal and is driving some oscillation. Where is the best place to filter…
Part Number: INA253 I have an issue of parts failing.
I am using the INA253A2 on the low (ground) side of a voice coil. I provides the current feedback for the Class A amplifier powering the Voice coil. The power supply for the amplifier is +/-30 volts…
Part Number: INA253 Hi,
I am designing where I have to measure current and I'll be using INA253. In unidirectional mode the datasheet proposes connecting REF1 and REF2 to GND, IN+ to the current "input" and IN- to current "output" (or: IN+ to the power…
Part Number: INA253 Other Parts Discussed in Thread: INA181 , INA180 , INA301 , INA290 , INA280 Hi expert,
I post it under INA253 because I cannot find other new suitable parts.
My basic requirement can be described functionally as below, does TI have such…
Part Number: INA253 Other Parts Discussed in Thread: INA250 Hello,
We selected INA253 and INA250 for current measurements in a HIL test rack application.
Can I ask you have a look at the schematic and layout below and give a feedback why the old setup…
