Hello,
Please look at the following diagram: When positive input is 0,the output should be 0v,while the output should be 5v If positive input is 1.8v.
However, now the output is 1.8v when positive input is also 1.8v.
The first solution I think is that: need I delete C5/C8? Maybe the first output is vibrate. But I can’t assure that.
The second solution: Can I use LMV358 instead of LM358 ? Because LMV358 is a rail to rail output amplifier. ( the
datasheet of LMV358: http://www.kynix.com/uploadfiles/pdf9675/LMV358AM8X.pdf )
Could anyone here give me some suggestions?
Best regards~
