Hi,KarenNE
I reaffirmed to report to our customers.
Please check because there was the following questions from our customers.
You wrote ripple is not visible.
Can you send me the waveform when you test?
>What input source is being used?
1. Measure the waveform of IN6 without entering.
The probing of the pin at the input ADAS3032 Open state.
2. Measure Ripple voltage when the input to the +5VA directly to IN6.
+5VA is the power of the evaluation board.
Power has entered a + -15V at KIKUSUI PMM35-1.2DU.
>When they removed the RC filters, did they probe directly on the input pin?
Yes.
Use equipment Tektronix MSO2024B, probe TPP0200.
>Also, do they see these issues on multiple boards?
I was confirmed evaluation board 1pcs, in our mounting board 1pcs.
CFG setting: PCGA GAIN 0.40 Vin = + is -10.2400V.
