Hi Ilmars Our customer is considering to reduce gain amp using delta-sigma A/D. Because delta-sigma A/D has high dynamic range. As you mentioned , their current system is used SAR A/D with gain amp.

These boards have neither a keyboard nor a display. There are libraries for commonly uses components, but that depends on which component you actually connect to the board
