#82696 - exceeding error budget Responding to: Steve M. Taylor's previous message |
Prahlad,
1) I have seen way too many "needs for recalibration" of things with a trimpot, you can use that method, but be warned. Trimpots are not very stable and "everyone" with a problem will tweek them, "just to see". 2) your solution with an OP7 is more expensive than a small eeprom holding a "correction factor". I am speaking from experience and take the advice or not. Erik |
