Other Parts Discussed in Thread: ADS1248
Dear Sir,
Our customer measured VISO ripple voltage, 90mVpp, 85us @ 5Vin-5Vout, 2mAout (drive only ADS1248). It is not an issue nor out of sepc, understanding typ 100mVpp and figure 30 in d/s.
However they would like to improve less ripple voltage if possible. An idea is to add LC in the 2nd figure below. Do you think it is the right way or have another good way?
It would be very appreciated if there is good recommendation to improve Vpp.
Best regards,
Masa
