Hello Wei,
Looking at your schematic, the DC voltage at LMV721-N output should be 1.6V (not 3.1 or 3.28V). Unless you are referring to the voltage at C2 (right hand side) plate which is dictated by whatever circuitry it is connected to.
Please clarify…
Hi Meiling,
I apologize for missing this. I read through your description again, and it seems like you want to have the op amp circuit detect the above waveform and wake the CPU up. I'm still having a bit of trouble picturing which node the input signal…
Hello Wiky,
There are currently two LMV721 - the original National LMV721-N, and the second source from TI, the LMV721. Duplicate devices from National got the -N suffix.
The graph you are showing is from the TI version. The noise graph does look…
Hi Holger,
I was reminded by a colleague that you can use the model for the LMV721-N: www.ti.com/.../toolssoftware , which is the single channel version of the device you're looking at. For typical specs and performance, the LMV722-N and LMV722 can…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
