Part Number: INA149-EP Hello,
I found a PCN 20140409000, for Wire material and diam change on INA149AID and INA149AIDR.
I would like to know if this PCN is applicable on INA149AMDREP ? (even if not precised into this PCN)
Best Regards,

My customer wants to use OPA4H014-SEP as a buffer between ADC and INA current sensor like below configuration.
And they found OPA…
Part Number: INA149-EP Other Parts Discussed in Thread: INA149 , Hi, Good day. Our customer wants to know the details of what has been enhanced in the INA149-EP compared to INA149 aside from wider temperature range. This question arises because our customer…
Part Number: INA149-EP The INA149-EP has an absolute max common mode rating of 500V for 10s. Can it take higher voltages for brief periods of time? Let's say 750V for 10ms? Assuming the 10s rating is a dissipation limit then shorter pulses could be possible…
Part Number: INA149-EP Team,
My customer needs some help figuring out whether a TI device can withstand a voltage transient.
I’m looking at the INA149-EP op-amp, and we have a transient of 750V common mode voltage at the op-amp inputs for less than 10…
Part Number: INA149 Hi,
I didn't find any curve about output impedance in INA149 (-EP) datasheet.
Does the spice model is representative for a "typical +25°C", on frequency range [1 ; 1Meg]Hz?
Best regards,
Emilien
Part Number: INA149-EP Other Parts Discussed in Thread: INA149 Hi,
We currently use INA 149 in our front-end and we rely on the "500V for 10s" characteristics to withstand lightning surge residual voltage.
Indeed, our customer has increase the…
Hi Xiaofu,
We do not have exact part 2 part replacement in INA149AIDR part. INA149AIDR comes with SOIC-8 package, INA149-EP will work, but it comes with higher cost.

Hi Benjamin ,
The only one that I found that is rated for aerospace and military version is INA149-EP, but the operating temperature is only rated from -55C - 125C. For automotive, you would prefer the operating temperature is up to 150C. So I am not sure…
