Part Number: ADS8688 Tool/software: Hello,
The customer needs to know the common mode rejection ratio (CMRR) parameter of ADS8688, but the data manual cannot be found. Please help provide it, Thanks!
Part Number: ADS8688 Tool/software: Dear the person in charge,
I’ m not sure if this is a technical issue or a bad one. Because I do not know how the end customer used it.
I attached the picture of the ADS8688 in problem. I found the burn mark…
Part Number: ADS8688 Tool/software: I am developing 8 channel analog input using ads8688 . output of ADC is varying approximately 30 counts in all the range. I am using
1) internal reference
2) same output ( buffered using op 07) is used for analog input…
Part Number: ADS8688 Tool/software: Dears,
In my system some ADC chans input no used.
How to connect for no used ADC input pins?
Floating or connect to GND? thanks.
Part Number: ADS8688 Tool/software: Hi
Raw data is recognized but noisy.
Below is raw data based on 0v.
Is the code below wrong? I want to reduce the noise.
Write_Cmd_8688Register(RST,DD,chip_sel);
Ms_Delay(100);
Write_Cmd_8688Register(NO_OP,DD…
Part Number: ADS8688 Tool/software: Hi team, I am using ADS8688 in my design. I am designing PMSM FOC but am unable to tune my FOC. I need to ask if ADS8688 is enough in terms of speed to be used in FOC. I am implementing FOC PMSM It requires sensing inline…
Part Number: ADS8688 Tool/software: I read that 15ms are required for device to power-up when REFSEL = 0(internal reference mode).
In my application, internal reference mode is disabled.(REFSEL = DVDD)
How long does it take to power-up?
Perhaps I don't understand your question here. Datasheets are usually written with the highest throughput of the device in mind. At full speed with a 17MHz clock, the conversion takes 850nS. If you slow down the clock, you slow down the throughput…
Dear Tom,
Thank you for your continuous support.
We have solved our problem by replacing a faulty 230 volts AC to 24 volts DC power supply with a working one. This 24 volts DC is used again to convert to +5.0 V DC, +3.3 V DC and +/-12 V DC which are used…
