#181911 - Some Questions! Responding to: ???'s previous message |
Dear Kai,I Simulated Your Scheme,Works Fine,
but there are some questions, 1-Can LM385 And U3 replaced with a simple r/r divider? it is for temperature drift!? 2-why you apply gain in the last satge? 3-is MCP6274 is a good choise for this application? 4-why 4 stage gain?why not 2 stage gain? 5-what about references like ad680 or ref43 ? 6-if dynamic range goes below 0.1v (8.6v to 8.7v)which gain is better to change? Thanks in Advanced |
