INA950-SEP: No Stock Available

Ryo Kimura

Part Number: INA950-SEP
Other Parts Discussed in Thread: INA951-SEP

I am looking for an alternative to this amplifier since this part is not in-stock. Would like to ask if you can suggest an option for a lower grade alternative.

Kimura-san,

I am assuming for "lower grade alternative" you are looking for -SEP level space devices? Please let me know if this understanding is correct. If not, I can provide some additional recommendations in automotive or commercial grade as well.

Regarding space grade SEP parts, the only other alternative I can recommend here is the INA951-SEP which has just released. This is a bidirectional, negative VCM capable device quite similar to the INA950-SEP, however, it has slightly relaxed specifications, but is negative common mode capable down to -4V. I have taken the liberty of generating a comparison table of the two devices here for you:

Mr Andrews,

Thank you for the prompt reply. We would prefer -SEP level alternative that is in stock but we are open to automotive and commercial grade if we need to go that route. This is a development unit and we will need all parts in hand by this July.

I noticed the INA951-SEP is not in production. If this works for our application will we be able to order and get it in our hands by July? We require less than 10.
