Thanks for your reply Mark. After reading more about Teensy I decided to go with an alternative processor (STM32+DSP), and I will indeed be using a separate PCB (own design) with 4x concurrent ADCs, LNA and other signal conditioning + fast data interface etc.

Hi Angelo, thank you.

Hi Tu I will have an external LNA and nyquist filter so the signal amplitude is under my control, target SNR is 80 dB, so 14+ bits resolution, or I can oversample and decimate if necessary.

Hi All, I'm new here and would be grateful for advice please. I want to develop a system that can do the following: capture up to four ADC samples concurrently and at up to about 200 kHz sample rate. When I say concurrent, I'd ideally like absolutely synchronous sampling, but a gap of...
