Part Number: ADS8638 Hi,
We are in the process of replacing an ADC in a design which has gone EOL. The TI ADS8638SRGER is an excellent fit, but I was wondering if it is recommended for new designs, or if there is a planned end of life date for this part…
Part Number: ADS8638 Hello~
I have a question about using the ADS8638.
datasheet Page 24. in text => "Whether it is an internal or external reference, be sure to decouple the REF terminal to REFGND with a 10µF capacitor. Place the capacitor close to the…
Part Number: ADS8638 Other Parts Discussed in Thread: TLV4171 Hi,
I am using an ADS8638 in my design to read +/-12V analog signal, it's working good with HVSS = -15V and HVDD = +15V. However I could save some money and space by using a +/-12V power supply…
Part Number: ADS8638 HI!
I have an issue with ADS8638 thru SPI communication
Once I read the register, The IC can't send anything.
is there any problem with schematic or communication control?
Here I attached my schematic.
Thanks
Part Number: ADS8638 Other Parts Discussed in Thread: ADS8668 Hi,
I am using ADS8638, 8 channel ADC for inputs of 0-10V. I am giving 3.3V as supply (DVDD & AVDD) and 10V for HVDD. Is it necessary to give HVSS mux voltage as -10V? Can I give 0V? How is…
Part Number: ADS8638 In page 64 of the DS, the section named "DRIVING ANALOG SIGNAL INPUT WITHOUT AN OPERATIONAL AMPLIFIER" describes the use of a bypass capacitor and the sampling rate for determining the output impedance of the circuit. Can you explain…

Part Number: ADS8638 Hi,
I am using ADS8638 in my design. I would like to know what termination resistor value need to be placed in the SPI lines and how to calculate the termination resistor values for the SPI lines.
In Datasheet, it is mentioned 50Ω…
Part Number: ADS8638 Hi,
I am using ADS8638 for the DC Voltage Measurement. Can I use the same to measure AC Voltage Measurement?
Max AC Voltage Range: -4V to 4V
Please do suggest me a DC and AC Voltage supported ADC, if not applicable with ADS8638. …
Part Number: ADS8638 Hi,
There is an issue about the accuracy of ADS8638. The failure percentage is 40%.
Input : DC 5V from power supply to AIN0-7 => Output value 0-7: 5.012V
Input : DC 0V from power supply to AIN0-7 => Output value 0-7: 12mV
Is this…
