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…
Hi Nick,
Thanks for the question. The reference selection tool seems to be parsing the voltage level data incorrectly. You may use a precision 5V reference like the REF5050. Please follow the guidance in the datasheet regarding decoupling capacitors…
Hello Michael,
In mode ADCs, the analog inputs can be driven as long as the analog supply voltage has ramped. In the ADS8910B, the Abs. Max Ratings table refers the analog inputs to VREF, so I would also check that the REF5050 output has at least started…
Part Number: TL594 Hello guys,
One of my customers is considering using TL594.
They want to know the manufacturing variation distribution data of "FEEDBACK" input sink current (Min=0.3mA, Typ=0.7mA) as a histogram graph like Figure 3 graph on page…

Dear Technical Support Team,
ADS8862 datasheet shows Charge-Kickback Filter and RFLT ≦ 22 Ω and CFLT ≧ 590 pF(Figure 62. Charge-Kickback Filter), but my configuration…
Hi Aaron,
The start up time is heavily dependent on the input cap and output cap. Due to how old this device is, I do not have the data on how it was originally tested.
Is there a reason why your customer is using the REF02 compared to the REF5050…
Sorry for not describe clearly :
- Which passive components do you need help defining?
The 2.5V REF is refered from this post : ADS1256 - Data converters forum - Data converters - TI E2E support forums ,
I'm not sure how did he defined these value…
Part Number: DAC7811 Other Parts Discussed in Thread: OPA350 , DAC902 , DAC80501 , DAC60501 Tool/software: My team is looking to use a SPI-controlled DAC to generate 0 to 5.5V analog signals with maximum frequencies of 1-2 MHz. We think the DAC7811 fits…
Randall,
That makes sense. In fact the Iq on VDD is probably even worse since now that rail has to supply both the REF5050 and the DAC80501 to fight one another. The REF5050 isn't even completely turned on, though.
