Part Number:ADS7823
Dear Sir,
Please refer to attached pic.
ch1 is SDA and ch2 is Ain of ADS7823 (pin2)
My customer found:
1. while they tried to read the Ain signal, the Ain signal will have ripple about 600mV Vpp.
Meanwhile, the value that got from ADC(red block 1) will difference with the data read from meter(red block 2) around 200~300mV.
2. if customer add 10uF in schematics of R31 and test again, the difference of value will low to 20~30mV.
Is there anything need to pay attention about this issue?
How to correct it?
Thanks.
