Hi Conor,
Sorry for the confusion - the LPF filter in the ADC needs time to settle after the input range is changed, the BW of LPF on ADS8665 is 15kHz which is the same BW as the option 2 filter on ADS8686S, so the settling time is also approximately 120us…
Part Number: ADS8665 Other Parts Discussed in Thread: ADS8661 Hi,
I am currently making a SPI driver code for ADS8665. If my driver code works well with ADS8665, may i check with you if this driver code will work for ADS8661 also? Since ADS8665 has a longer…
Part Number: ADS8665 Tool/software: As a test - I'm trying to Read & write the value of PAR_EN bit / byte 1 of DATAOUT_CTL_REG. (Pg 51 of the the sheet - for some reason it won't let me paste an image here.
As I want to read an even address…
Hi Ben,
You would have to write a 16 bit data write command to address 26h to set INP_ALRM_HYST, and the another 16 bit data write command to 24h to set INP_ALRM_HIGH_TH. You cannot write to 25h or 27h, as the address must be even.
For example, to set…

Part Number: ADS8665 When I read the datasheet, I see that AIN_P and AIN_GND pins are designated for positive input. I want to provide a negative input in bipolar mode. How should I make the connections?
Part Number: ADS8665 Other Parts Discussed in Thread: MUX508 , ADS8661W We are using ADS8665 in our design. To read up to 8 analog inputs, MUX508 is used to switch between channels. My question is, what is the signal settling time across 8665 AFE when…
Part Number: ADS8665 Hi,
Is it possible to disable internal 15kHz LPF?
Customer is taking samples at every 45us and because of internal LPF cutoff frequency 15KHz signal is getting attenuated. Do you propose any solution for this issue?
Part Number: ADS8665 Hello,
My project is having problems to read the Ads8665 spi credibility, and to know if the
ads8665 has in fact even booted.
The data sheet states that RVS should go high 20 ms after RST/ goes High.
If also, I raise the cs/ to High…
