TS922AIN vs TS922IN

Hi,

Can someone clue me in what's the difference between TS922IN and TS922AIN? Can I easily substitute TS922IN with TS922AIN in existing project? From datasheet it seems like only difference is "Input Offset Voltage" which is 900uV max for TS922A. Reason I'm asking is that TS922IN has been retired :(

I didn't look at the datasheet, but it's not unusual for "A" part to be a better or newer version. (Although, you do have to check because it could operate from a different voltage or have a different pinout, etc.) A lower offset voltage is better.

Hello bratan, You are right about 922A IOV but I don't see TS922AIN active at STElectronics. Only AID, AIDT, AIPT, AIYDT and AIYPT (none of them is DIP-8). Regarding TS922IN STE still producing it but supporting only ongoing production, AVNET keeps 1278 in stock and Future Electronics keeps 1550. Farnell and RS Components (both in Europe) with a bit over 1000 in stock each. Good luck.

Oh no, so TS922AIN is also getting retired? I'm working on a new project, I guess I don't want to design it with part that will be gone in a year or so... Can anyone recommend comparable substitute? :)
