Hello:
Please recommend a driving power operational amplifier of resolver which is close to ALM2403-Q1 in function，My client wants industrial grade not automotive grade，Thanks！！！
Hi Jimmy,
The industrial grade vs. automotive grade differ mainly in the operating temperature range. There are other value added features such as functional safety capable and/or stringent fab process. In general, automotive grade has higher reliability than industrial grade parts. ALM2403-Q1 is specifically designed for automotive environment and applications, and its functionality will exceed industrial grade.
In terms of unit price, automotive grade may be a lower in cost (in general) It is not because of it is inferior, rather its quality and fab process are optimized in order to compete for pricing. Typically, automotive grade parts are high in volume and demand due to its application. If I had a choice in selecting a part, I would select automotive grade over industrial grade at any time.
The captured image below is the grade differences in guaranteed operating temperature.
In ALM2403-Q1 resolver IC, we do not produce industrial grade in this part. ALM2402F-Q1 resolver is similar to ALM2403-Q1 with some specification differences in operating voltage range and output current etc..
If you have additional questions, please let me know.
Best,
Raymond
