Part Number: ADS8661 Hi Team,
May I ask a question about ADS8661, in the datasheet, sampling frequency is 1.25 MSPS, but input bandwidth is only 15k.
Previously I used another ADC IC which sampling frequency is 500ksps and –3dB Input Linear Bandwidth is…

Hi Team,
I want to check the procedure of reading voltage by using ADS8861. Would you help check below procedure for us? Thank you.
Platfrom : Raspberry Pi, SPI speed, = 15.25878906kHz

Part Number: ADS8661 Hello,
I am using stm32h7, and I am able to read 12 bit ADC values from ADS8661 IC through HAL_SPI_Receive() as shown in the code (per loop it is taking 13us), but when plotting and calculated the sampling rate, I am only able to…
Part Number: ADS8661 Other Parts Discussed in Thread: ADS8688 Do u have the IBIS module of the ADS8661 or some similar ICs for us to use? We want to have the IBIS module of ADS8661(8 daisy-chain) to go through the SI simulation。 Thank U.
Part Number: ADS8661 Hello,
I've been looking up at driver files for this IC [ADS8661] couldn't find it online. I am trying to develop it with STM32H7 . If someone has created it please share it .
Thanks and Regards,
Vibeesh
1. Done.

Q: I'm curious why you are sending only 7 SCLKs instead of 12 or 16 SCLKs to the ADC every time.
A: When using dual SDI MODE, SDI single only exists in the first 6 clock cycle. I use 7 clock cycle to speed up conversion, last clock cycle…
Part Number: ADS8661 Other Parts Discussed in Thread: ADS8688 , ADS8674 , ADS8665 Hi All,
I bought a ADS8661 . I want to program this device but I couldnt find any Application Note for development. Is there any example or any code for the program.
Th…
Part Number: ADS8661 Hello,
I am trying to work with the device but with no success, the datasheet is not clear enough.
1) I am using SPI MODE0.
2) I am sending data in 8bit data groups (same when receiving data) ie sending 8 clocks at a time, hence for…
Hi Luke,
Both ADS8661 and ADS8681 definitely should work for analog DC input or 1KHz sinewave signal. The glitch you observed was caused by something else in your system. When you check glitch on the analog input, make sure you have proper settings on…
