Is there any issue with this configuration? And i have read in some books before that we can make non-polar capacitors this way...bit unfortunately i don't recall the book.

Is there any issue with this configuration? I want to have a high voltage non-polar and cheap capacitor(around 3-4uf 400v). they will act like a resistor and they so I can use a secondary zener and low enough resistor to...
Cheap way of 16bit analog accuracy Quote:But I'm still curious why 16 bits are needed?
Because they say it's 16bit but the actual effective number of bit's are lower. For k20 series it's about 14.5Bit.
And if you...

Cheap way of 16bit analog accuracy Quote:It looks like Moores law brought us more fore less, once more
Kinetis series from freescale even are more wiser choice devices! They are cheap and 32bit, have 16bit adc and...
Cheap way of 16bit analog accuracy Quote:Money is what its all about!
I certainly agree with you. I want to use the whole system for building a digital power supply. And the thread that markus_b send is a gift...
Cheapest MCU and power suplly. Quote:Commercial or hobby? If commercial, what sort of quantity?
of course commercial, it’s where the price always matters.In the order of 1k units. What are your suggestions...

What are the demands on this "RTC"? Is the RTC of the ARMs something like the separate RTC chips, temperature compensated, calibrated and all that?
Or are you simply after...

Cheapest MCU and power suplly. Because it needs an internal RTC, and Old AVR's do not have them, and recently I have seen cortex m0, they are achievable in 1usd in 1k qty.
The parts can be anything, but no BGA...
Ok, if it's not a good option,how can i have 5v @ 200ma around 1USD?

Guys what’s your opinion about Ref voltage Chip. I think ADR421 is a good candidate.
