I need to read 3 ADC channels simultaneously, where the frequency will be maximum 400kHz. The waveform will be sinewave of +/-2V (peak to peak) The data must be stored into an SDCARD and read using a PC, it can be a CSV file. Multiple files are OK as long as they can be joined together and uninterrupted in recording. Prefer to us ANALOG Devices ICs. Please advise.

3 channel 16 bit ADC recording. Can we use Raspberry Pi for this project, because it readily has SD card interface and Ethernet interface through which data can be transferred to PC. We can design an addon card to raspberry Pi with a 24 bit ADC like ADS1298 and extract MSB 16 bits out of it and deliver to raspberry pi or we can use a 16 bit ADC (TI or Analog devices) Can we discuss further details?

Hello, I am interested to work on this project. From description is not quite clear if you need max 400kHz of ADC conversion rate or you need to read sine wave with max frequency of 400kHz, in this case ADC conversion rate should be much higher. For fast ADC it might be possible to use FPGA development board fitted with custom SD card reader and converters. If 400kHz ADC conversion rate is OK, it should be possible to use fast micro controller to get readings from ADC ICs and save data on SD card. Send me a message me to discuss further requirements.

Sounds really interesting. You'll need to write a few megabytes of data per second and capture at a rate of 1.2 MHz too. An atmega328p can handle that but I suggest not using Arduino but programming directly. For an ADC there is a plethora of options out there, how many bits of accuracy do you need? I am an electronics expert and an avid programmer. Pl. let me know if you have any questions.

You could use Arduino Due which can reach the clock speed of its I2C upto 400 kHz. So, simply read the data from analog pin and store on SDCard as well.

My proposal is to make a design with the standard CHIPKIT MAX32 Board from National Instruments. It can read analog channels directly. I think is the better option for a single or low units prototype. Files could be accessed by FTP with an ethernet interface, they also cane stored in a SD Card un FAT32 to be read from a computer. If you want to make a board for large series I can make you a custom board. We can discuss it at the chat.
