Part Number: ADS5272 We have been using this A/D converter successfully for a long time but introduced a new vendor with different analog characteristics which indirectly feeds the A/D. When we have issues we are seeing a drop in 3.3V current and incorrect…
Part Number: ADS5272 Hi Team,
Need your help regarding ADS5272 output coding scheme. Is the "Straight Offset Binary" the same with Bipolar Offset Binary in the below document? The ADS5272 datasheet states that a differential input of –1V corresponds…
Other Parts Discussed in Thread: ADS5272 I've built a custom board with 4x ADS5272 on it and I'm finding some strange behavior in normal ADC mode. When I first power the chips up, they all output a fixed pattern on their serial data outputs. Each channel…
Hi,
i would not expect to see a periodic signal on the serialized data, or even to recognize periodic patterns within the bit positions of the serialized data relative to the frame clock edges. I think the data would need to be deserialized first.…
Couple of quick things Akash,
1. Where is your DC bias current path for the V+ inputs to the op amps?
2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
