Other Parts Discussed in Thread: TIDA-00366, AMC1100
Dear TI team,
In Tida-00555,in voltage sensing you have used 332K five number in series to reduce AC voltage and connected 1K across to get around 230mV for maximum 270V AC RMS.
While we do kirchoff voltage law(KVL),we can find out that current is around 230uA(270V AC RMS).
So you have used 332k,1206 package,1% tolerance thick film resistor 5 number in series which is 1.66Mohm.can we use 1Mohm(thin film) and two 332K(thin film) in series or only one 1.66Mohm thin film resistor with 1k voltage divider?
Can we use lesser value like 100k(5 number) in series to get 500K and 280 ohm across to get 210mV approximately?
I'm getting noisy waveform after 1.66Mohm and 1k ohm voltage divider,may I use above 100k(5 number)and 280 ohm voltage divider combination?
is Tida-00555 and Tida-00366 fully tested? can you share output wave forms and more details of Tida-00555?
