Does anyone have any insight into which device is likely to have the longest product life (out of ADS1248 and LMP90100)?
Our initial design used the LMP90100 but we are considering changing to the ADS1248 because:
1. Difficulty performing synchronised conversions when using the internal IDAC
2. Poor uncalibrated gain error (with and without input buffer)
The ADS1248 is more expensive but is easier to use, has better noise performance and much better uncalibrated gain and offset errors.
One remaining concern we have with switching is the product life. Both are listed as 10 years in Silicon Expert.
Anyone know anything more?
Thanks,
Ken.
