ads1251 schematic
I am in the process of designing a circuit with a 24-bit adc on it. I am wondering if i should devide the ground plane (4 layer with sig-5V-GND-sig) up into digital and analogue. This particular adc (texas ADS1251) does not have a digital supply input. So should i just have one unborken ground plane, at present there will be no digital components on this board, but at a later stage we might put a micro on the board to read data out of the adc.
Really just looking for advice or experience with an adc with such high resolution?
