Hi Wlliam,
the reason for the error is that you violate the common mode input voltage range of INA821. You must stay at least 2V away from the supply rails at the input:
One remedy is to increase V1 from +4V to +5V. Then you wouldn't violate the common…
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA281 Hi, Could you please help me with an application of the INA281B4? I'm using it in a high side buck convertor current sensing application and it doesn't seem to like the common mode range even…
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA193 , INA281 Please let us know the reason why IB and Iq values of this part are larger that INA193-Q1.
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA280 , INA281 Hello, I am using the INA281A1-Q1 in a configuration for high-side current sense of a 50V supply. The Vs pin of the current sense amplifier is powered at 3.0 V. When the 50V rail is…
Part Number: INA271A-Q1 Other Parts Discussed in Thread: INA271 , TINA-TI , INA281 Tool/software: Looking for IBIS Model for Part Number "INA271AQDRQ1".
Part Number: INA181-Q1 Other Parts Discussed in Thread: INA296A , INA281-Q1 , INA240-Q1 , INA241A , INA293-Q1 , INA190-Q1 Hi Expert,
May you kindly suggest one device with similar spec but higher CMRR than INA181-Q1? And they are pin compatible.
Thanks!

Hey Harry,
The only way to improve this for INA214 is to provide a small reference voltage to REF pin (> 50mV). This will ensure OUT is always in linear region.
The other option is to simply use a faster device such as INA181, INA280, or INA281. The…
Part Number: INA186-Q1 Other Parts Discussed in Thread: INA186 , INA190 , INA213 , INA296B , INA185 , INA280 , INA281 , INA181 Hi
I have encountered an issue with INA186A2-Q1 I am using in one of the designs.
The schematic is attached bellow. I use a DCDC from…
Hey Shinichi,
Since this behavior is not tightly controlled there is no specification. However, based upon testing we have done, it seems like the overload recovery delay may only last up to 80 µs assuming a -70mV input. I would say that you would need…
Part Number: INA194A-Q1 Other Parts Discussed in Thread: INA293 , INA194 , INA290 , INA281 , INA280 Please let me know if there is accuracy better than the INA194AQDBVRQ1. Also, if there is an isolated current amplifier that is inexpensive and has good accuracy…
