Other Parts Discussed in Thread: INA250
Hi Sir I have some questions about INA250 as followings.
1. What is temperature coefficient maximum value？The datasheet only describe typical value.
2. Do you have longtime testing report？ (over 1000hrs)
3. Could you provide offset value for voltage unit？The datasheet only describe current unit.
4. When INA250A1 release？
Thanks for your support.
Hello Hugo,
1.Regarding temperature you are correct in that we only have typical values and we will not have a maximum value. Please look at figure 26 from the datasheet for the typical resistance change vs temperature.
2.We currently do not have over 1000hr testing.
3. To calculate the offset in voltage we just get max error in current * typcical resistance
+/-50mA * 2mOhm = +/-100uV
4.It is expected to be released in the first quarter of 2016.
Thanks,
Javier
