Other Parts Discussed in Thread: INA236, INA228, INA238
Tool/software:
Hello Team,
I was calculating current measurement error using your Current_Sense_Amplifier_Comparison_and_Error_Tool and got the below results.
However, I have few queries as follows:
1. Is ENOB value considered in the tool to calculate error in lower range ?
2. What output sample period is considered during the ADCRANGE & ENOB selection if applicable ?
3. Why there is no change in error value if I use INA236 full scale ADCRANGE 1 (±20.48-mV) or ADCRANGE 0 (±81.92-mV). Both selection showing same error under same condition.
4. Why aren't INA238 & INA228 having option to select different ADCRANGE ? Are the results same ?
4. Is external common-mode filter will reduce the error or was it considered to calculate Ibias ?
