Part Number: INA253EVM Other Parts Discussed in Thread: INA253 Tool/software: Hi,
The diagram below is the datasheet provided by Texas Instruments of INA253. Under page 5, the nonlinearity error given is 0.01% as highlighted.
My question is what does…
Part Number: INA253 Other Parts Discussed in Thread: OPA1655 , Tool/software: Hi,
I am investigating driving high end speakers with a current output amplifier rather than a voltage output amplifier.
There are several reasons to do this, see the book ISBN…
Part Number: INA253 Other Parts Discussed in Thread: TINA-TI Tool/software: Hi,
Theory Part
I have tried to run a test by using the software called LTspice. Below is the construction of my circuit. As observed below, the model "U1" that I use is INA253A1…
Part Number: INA253-Q1 Other Parts Discussed in Thread: INA240 Tool/software: I plan to use INA253A3-Q1 for current sensing based on the orginal current requirement of RMS 3A, but recently we got a requirement change, the RMS current will be max. 0.8A…
Part Number: INA253-Q1 Other Parts Discussed in Thread: INA253 Tool/software: We want to use INA253 for current sensing, could you pls support to calculate if it can meet our accuracy requirement? thank you.

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…
