Part Number: ADS8638 Hi,
My customer design ADS8638 as below cirucuit, and the power source is described in below figure.
Their application is vibration.
The input signal is 3.3V from power supply.
Sampling Frequency is 25KHz.
And they found that there…
Part Number: ADS8638 Hello All, I need to use the ADC8638 for 8 ch voltage conversion, it has a good sampling rate and a good resolution, but something came in mind. I see in its datasheet that HVDD and HVSS could be up to plus/minus 15 V, but recommended…
Part Number: ADS8638 Hi,
what happens if we left the thermal pad and the pin #4 not connected and floating in the ADS8638?
it is recommended in the datasheet to connect them to: pin #4 to ground and thermal pad to the PCB. However, we found out that too…
Part Number: ADS8638 Thanks for the link to teh schematic, there is another question
One question about the ADS8638 EVM please, do we need to power the
> HVDD and HVSS pins from somewhere? (i.e. an external PSU)

> It's not completely clear from…
Part Number: ADS8638 HI Team, the documentation says there is a schematic, but is does not seems to be there, just the Gerbers- is there another location I can get it from, also can i get the mother board schematic from the PDK evm bundle
Part Number: ADS8638 On the testing ADS8638 by 0V~5V input and 12bit resolution.
Expected value is 0V: 0x000 and 5V: 0xFFF, but result was 0V: 0x800 and 5V: 0xBE2. (I think that these value was received on ±10V range condition)
Please let me know…
Part Number: ADS8638 Hi again,
I am using the ADS8638 in "manual" channel sequencing mode, i.e. I send SPI commands to the chip to manually select a particular ADC input channel. From my microcontroller, for testing I have a continuous loop which sends…
Part Number: ADS8638 Other Parts Discussed in Thread: INA149 Hi Sir
I saw ADS8638 datasheet have a battery cell voltage monitor used with INA149
Have any ADC could be used for this application without INA149?
Thanks
Part Number: ADS8638 Hi, I have noticed when using the ADS8638 that the first couple of reads of the ADC return "junk" data, after that it seems OK.
The command I am sending is 0x0810, which is a manual mode read for channel 1 (register address…
