I want to use adc with 16 bits resoloution and at least 32 ivoltage input channels or higher. And this is to important for me tha adc convert all adc in same time . at first I chose ddc 232 and after that I understood that ddc 232 is current input but i need voltage input. can you help me to choosing thr true adc.
The DDC232 is very low sample rate.(About 3k~6kSPS data rate.)
Could you provide some details of the applicationfor us to suggest the right ADC?
Thank you.Best regards,Chen
Although DDC232 is a current input ADC,
you still can input voltage signal
by soldering a resister R in series
(between your voltage input and DDC232 current input pin).
And also the resister R can not be too small value or too large value.
For example, if you want to input a voltage sine wave (0V ~ 3.3V),
please check the output of the data converter.
If the output signal is too small, then the R value is too large.
If the output signal is not very linear, then the R value is too small.
Please try it.
And welcome to let us know what you can obtain.
Thanks and best regards,
