Part Number: INA117 are there any power supply sequencing considerations for the INA117. For example, if -5V negative rail is applied first and then +27V positive supply rail, how would the output stage behave? Is this a valid sequence? Or is it recommended…
Part Number: INA241A Other Parts Discussed in Thread: INA290 , INA280 Hi, TI expert
I'm trying INA241 in my project but I'm wondering if it can be applied to sensing with much higher output voltage, so what is the highest common mode voltage that…
Other Parts Discussed in Thread: INA117 Hello,
I am wondering if there is any difference in temperature rating across different orderable devices, for example across INA117sm vs. INA117ku.
Thank you,
Rachel
Hi,
The output maintains milliamp accuracy across most of the operating range, but as your load increases and the voltage at the input of the INA increases you will see some degradation in this accuracy. The error is dominated by the offset of the INA117…

In our design we are measuring current(range 4mA to 500mA).
can you please suggest this current measurement part part number.
Thanks,

Other Parts Discussed in Thread: INA148 , INA117 hi,
I am looking for an opamp to implement signal conditional circuit which has high common-mode input range 0 to 300V. it must allow variable gain from 1 to 10. Found the competitor part LT1990. INA117,…
Hi Luis,
Your suggested changes to the RC input filter have made a significant improvement. Here is the new schematic (using the closest RC values I had available).
Also note my sampling rate is currently set to only 12.5 KHz. Is there more optimal RC…
Other Parts Discussed in Thread: INA117 , TINA-TI , INA149 Hello,
I am using INA117KU to sense a current going to my DC motor on the high side. The max. voltage across the motor is +/-36vdc (travels in both directions). The sense resistor is 0.1 Ohm. I have…
