#88940 - Digital Pots Responding to: ???'s previous message |
A suitable digital potentiometer might serve your purpose. What level of precision is required for the feedback resistor? The problem with digital pots is that they have a certain minimum resistance per step.
If a very very high precision is required, I would use fixed resistors with some sort of software controlled switching. Edit addition: Sorry, posted in the wrong thread, it was a reply to Prahlad's Three Gains post. |
