Part Number: ADS8686S Dear TI Team,
what is the silicon manufacuting process of the ADC?
Is there a SEE failure rate available for the ADS8686S and/or additional information regarding used resources depending on the operation mode (Hardware or Software…
Part Number: ADS8686S Hi,
what is the output voltage of REGCAP and REGCAPD? This is not specified in the datasheet, but needs to be clarified for selection of capacitors with appropriate voltage rating. From Figure 7-21 "ALDO vs Expected Output Code"…
Part Number: ADS8686S I am using an ADS8686, I am using it with a SPI bus and only the SDOA. I have everything working with commuications it seems, the problem I have is that when I tell it to conversion start I never see the busy signal go high. I have…
Part Number: ADS8686S Hello,
ADS8686S uses SPI serial communication and software mode; SDOA single line data, terminal configuration with a ± 5V range, normal operation from the beginning, calibration coefficients correct, and suddenly the code value…
Part Number: ADS8686S Hi team,
Please kindly refer to SCH and register from my customer. They used to adopt parallel interface and the ADS8686S works well. While recently they change the design to serial interface and the output data is not stable anymore…
Part Number: ADS8686S Hello,
Datasheet update
Regarding the following datasheet version: The electrical characteristics Table mentions the MIN and MAX values with a foot-note that this is "Preliminary Specifications, subject to change based on characterization…
Part Number: ADS8686S Hello,
The Datasheet gives the following formula for Analog input current calculation:
Is V IN the differential voltage between AIN_nX and AIN_nXG? Or is it the absolute voltage of each pin against AGND?
Regards Sebastian
P.S.: When…
Part Number: ADS8686S Hi team,
In below picture, green curve is CONVST, yellow curve is BUSY. The second BUSY high level is influenced by the abnormal CONVST, and customer found that it is caused by SCLK, while the conversion is on-going at this time…
Part Number: ADS8686S Hi, I am confused by the datasheet.
In 7.3.4, it mentioned to enable the 20% over-range function needs to write reg. D[7:0] of 0x08 and 0x0A for AIN_xA and D[7:0] of 0x09 and 0x0B for AIN_xB. But, there is no such reg. 0x09 in the table…
Part Number: ADS8686S Hi Team,
My customer is having some issues with SPI interfacing of ADS8686S, can you please help provide with an example circuit of SPI interfacing options of ADS8686S, with single SPI out (for both simultaneous channels, A and B) and…
