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: 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 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: 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…
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…
Other Parts Discussed in Thread: INA281-Q1 , INA168-Q1 , INA138-Q1 There is no mention of any automotive qualification standard for INA170EA Current shunt in its datasheet, can we use it for automotive applications,
If not suggest us the alternate current…
Part Number: INA293-Q1 Other Parts Discussed in Thread: INA293 , INA240 , INA281 , INA290 Do the INA240, INA281, INA290, and INA293 have rise time, propagation delay, and response time data? I only see settling time on the datasheet. I'm looking to compare…

Hi
Is it possible to measure the phase currents of a three phase motor control application with the INA293-Q1? I used the INA240 before and this…
Part Number: INA286-Q1 Other Parts Discussed in Thread: DRV8300 , INA286 , INA281 , INA240 , INA293
Hi,
I'm trying to build a custom motor control board, using a C2000 uC.
As a driver IC, I use the DRV8300 and for current measurement, I use the INA286…
Part Number: INA271 Other Parts Discussed in Thread: INA281 Hello guys,
One of my customers is evaluating INA271 on their own PCB for their new products.
They compared two INA271 output voltage on same PCB when the differential voltage between IN+ and…
