Part Number: ADS8862 Tool/software: Hi team,
My customer has nonlinear problem, could you help to explain about below figure?
For the INL max ±2.0LSB, if this means all influencing factors do not add up to the maximum？
Hi Dale,
Thank you for your support.
According to your summary of settling error, RFLT=25kΩ of c harge-kickback filter for Simulation 3.
How do you calculate it? Is the correct value RFLT= 25Ω?
Figure 62. Charge-Kickback Filter shows RFLT ≦ 22 Ω…
Part Number: ADS8862 Other Parts Discussed in Thread: CC2530 Hello,I want to drive ADS8862 to communicate with cc2530 recently,but I have met some problems.I sure I drive SPI successful that they have already communicated,and I can read some numerical value…

Dear Technical Support Team,
My configuration is ADS8862+REF6050.
There is CL+RESR(REF6050 DS shows 5mΩ+47uF) on output OUT_F/S .
I refer the REF6025EVM-PDK…
Hi Jackson,
Thank you for your reply.
Application is ADS8862(680ksps) reference voltage for 5V.
MY board has REF5050 so I will try to change from REF5050 to REF6050 for improving settling error.
Following are configuration on the universal board( Stri…
Part Number: ADS8862 Hi Team,
We have designed a circuit for ADS8862(it should be ADS8862 in the schematic) as shown in the picture below:
We found that there is noise on Vainp, which has the same frequency with sampling frequency(100kHz).
However,…
Hi Don,
Yes, your summary is correct.
When the device supply drops below minimum required operating voltage (either during power-up or normal operation), it is recommended to ramp down the power supply to 0-V and power-up again.
Thanks.

Dear Technical Support Team,
I have Output Oscillation issue with 2700pF on output.
The configuration is buffer for ADS8862.
When Riso is inserted on output, then output seems to be stable…
Part Number: ADS8862 Other Parts Discussed in Thread: ADS8881 , ADS7056 , ADS7853 , ADS7042 We have a spectrum analysis problem where we need to analyze a signal in the 490 kHz to 520 kHz range.
The signal will be bandpass filtered before sampling occurs…
