Other Parts Discussed in Thread: TMP235
One of my customers is evaluating TMP709. They have the following questions about temperature accuracy and response speed.
Could you please tell me your answer to their questions?
1. What does TE(Temperature error:+/-3 degree C as the Max) mean?
TMP709 temperature threshold level is set by resister value connected from SET pin to GND and this resister value can be calculated by equation (1) on page 8 of the device datasheet.
Is TE calculated with the case of exact resister value calculated by the equation (1) connecting?
Or is TE calculated with the case of 99%~101% of resister value calculated by the equation (1) connecting?
2. I think TMP709 has delay time from TA temperature reaching to threshold temperature to assert /OT signal because some temperature propagation time from TA to TJ is needed.
Do you have any data about the delay time or temperature response time?
Your reply would be much appreciated.
