Part Number: ADS8339 Tool/software: Hi all,
Analog signals are input to MCU using ADS8339.
The lower 3 bits of ADS8339 are become biased towards 1 or 0.
For the Vref and Vbd parts
It is improved by adding capacitor capacitance.
1)Is the approach that…
Part Number: ADS8339 Other Parts Discussed in Thread: ADS8319 , Hi,
Our customer use ADS8339IDGSR for products in mass production.
1. Is there a product that can be replaced from ADS8339IDGSR without changing peripheral circuits or software? (Other than…
Part Number: ADS8339 In the ADS8339 datasheet, it list out that the SLCK requirements have a 0.45-0.55 tclk LOW and HI time for the clock. I take this as the duty cycle of the clock must be 45-55%. Is that true? We have an application where the reader…
Part Number: ADS8339 Hi,
The reference input current spec is 75uA +/- 20%. Is this current the average over a single conversion time? If so, it is the average of the CDAC current spikes, correct?
The conversion time spec is very wide, 500ns - 3.3us. What…
Part Number: ADS8339 HI
My customer asked me as below.
1. If I input 4.096V in REFIN, what is the value of Digital output? 2. What is the value of Digital output if it is 4.096V input to REFIN and the IN+ value is greater than RFFIN? 3. I configured the…
Part Number: ADS8339 Hi sir,
There are REFIN and VREF in the data table. Are they the same?
If they are different, what are their differences.
If they are the same, why do they describe them separately?
In addition, if + VA = 5V,
What are the advantages…

Hi everyone,
I'm currently working on an ECG acquisition test-bed for analog front-ends. The ADC of choice was the ADS8339 to sample the…
Part Number: ADS8339 Hi sir,
I have a question on resolution of ADS8339.
I think full scale input span is according to the value of Vref in the datasheet,
but for full scale input span, it's determined by resolution 16bit.
e.g. if Vref= 3.3V, LSB…
Part Number: ADS8339 Other Parts Discussed in Thread: REF5045 , THS4281 , , REF3240 , OPA140 , ADS8864 , REF6045 , OPA350 Hi Team,
1. In the ADS8339 EVM, REF5045 is buffered by THS4281 then sent to the REF pin of ADS8339. I'm also aware that our REF6xxx family…
Part Number: ADS8339 Dear teams,
Our customer using ADS8339 in his application. The VDD and Vref are all 5V. -IN is connected to GND. A 0-5V signal is connected to +IN. When the input signal is 0-2.5V, the ADC output signal is 0x0000-0xFFFF. However, when…
