Part Number: ADS8638 Hello,
We currently have the ADS8638 designed into one of our products and it works well for reading the analog input data, however, we are having issues when we try to read the internal temperature channel.
The datasheet shows the…
Part Number: ADS8638 Hi,
In the datasheet, sampling starts at CS falling edge.
At auto-mode, If CS is continuously low without power down command in DIN and 1 data frame is passed, does ADS8638 not work?
or ADS8638 is continuously sampling and Dout is…
Part Number: ADS8638 Hello,
I use ADS8638 in my design.I have problem in reading conversion value.I can write to the configuration registers and when I read the value of the register, I can get the correct value. But when I read the conversion value,I…
Part Number: ADS8638 I'm working on a design that uses the ADS8638 to convert several different analog input for analysis on a linux-based computer. The problem I am having is reading any conversion data values. I can read and write to the configuration…
Part Number: ADS8638 hi guys i am having issues with reading from this chip. something is missing. i am sharing my code below. would anyone be able to help and share his code with me. many thanks.
#define ADC_TI_CHANNELS 8 // total number of channels…
Part Number: ADS8638 Hi:
I use ADS8638 in my design. I fined that when I supply the HVDD=15V and HVSS=-15V,the device becoming very hot in a short time,while there is no problem if I supply AVDD=3.3V and DVDD=3.3V in the same time . What's wrong with…
Other Parts Discussed in Thread: ADCPRO I have been having issues setting up and using the ADC evaluation kit, the ADS8638EVM. I am using windows 8 so that may be part of the problem, but after following the manual's instructions on setting up the board…
Other Parts Discussed in Thread: ADS8638 Hi,
Detailed problem description :
We have our Custom Board ,in Which we are using ADS8638 , It Reads the Value for 1 Hour and then it Starts Showing 0.0 Values in all the Channels.
Again Power Off and ON the ADC…
Hi Fabian,
Yes, I understand. High precision resistors get expensive very quickly as well. We do not currently have an ADC that can directly connect to 260V. This device may be able to meet your needs however https://www.ti.com/lit/ds/symlink/ads8638.…
