[Micro_brain]

Dear Friends

AD536A is a "True RMS-to-DC Converter" but it is costly
any other idea for "True RMS-to-DC Converstion"

Thanks Micro_brain

Can you give more detail on you application, we need to understand the performance cost metrics of your project
The chip cost $20. You can use a microprocessor with RMS SW but for small volumes that will be more expensive due to development costs
