Part Number: ADS8864 Hi,
We use 4 pcs. Of ADS8864 in daisy chain connection without busy indicator as described in the datasheet:
In datasheet it is stated:
A total of 16 x N SCLK falling edges are required to capture the outputs of all N…
Part Number: ADS8864 Other Parts Discussed in Thread: OPA320 , OPA2381 , Hello,
I am designing circuit for digitalization signal from photodiode. I am thinking about connecting the TIA directly to the input of ADC - I think it can be enough for driving…
Part Number: ADS8864 Hi there,
We are using your ADS8864 ADC in one of our designs and have noticed (occasionally) that when the system is powered on but with an unstable supply (we know this is due to mechanical switch bounce), the ADC simply locks…
Part Number: ADS8864 Hello Team,
can you clarify the following points:
Tsample is defined by tconv_max and tacq. Tconv_max is 1300ns so that 1200ns are left for tacq (which is at the same time the minimum for tacq) to reach 2500ns tsample (400kSps…
Part Number: ADS8864 Other Parts Discussed in Thread: ADS8881 Does analog input pin include ESD protection function?
If you have a feature, how much capacity?

Part Number: ADS8864 Hi all Would you mind if we ask ADS8864? <Question1> When we use ADS8864 with REF=4V、AVDD,DVDD=3.3V, there is no problem, isn't it? <Question2> What is AVDD used on the block diagram? We could not find where AVDD is used for. (Is…
Part Number: ADS8866 Other Parts Discussed in Thread: ADS8864 , 1:Hello, may I ask why Tconv in ADS8866 specification book is 500ns~ 8800ns time difference so big?And ADS8864 specification book Tconv can achieve 500ns to 1300 ns time difference is small…
Other Parts Discussed in Thread: ADS8864 Hi,
In the ADS8864 datasheet, Figure 37. POWER-DOWN CURRENT vs TEMPERATURE shows "mA" in the vertical header. Should this be "nA" ?
Thanks,

Hi Jose,
I'm not sure what your exact problem is, if it doesn't work when you use 4-wire without bus indicator shown in below figure 1, please upload your timing screenshot for digital signals and it will be helpful to figure out the reason.
If you…
Other Parts Discussed in Thread: ADS8864 I’m reading the data sheet for the ADS8864 and I’m a bit confused as to some of the terminology. On the front page it states.
“ The ADS8864 is a 16-bit, 400-kSPS, single-ended input, analog-to-digital converter…
