Part Number: ADS8339 I am currently designing a board using the ADS8339, where the SPI signals are routed off-board to a customer's secondary board. I would like to seek your advice regarding the placement of damping resistors for the SPI interface. …
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…
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 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…
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…
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…
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…
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,…
Hi Keith,
Thank you very much for clarifying my questions.
I need two reference drivers, one for the DAC and another for the ADC, the DAC driver is necessary because of the RC low-pass filter, this driver doesn't require a capacitor at it's output…
