Buying advice

Select an ADC based on the required resolution, sampling rate, channel count, and interface type. High-speed or high-resolution parts deliver better performance but increase cost, power, and PCB design complexity, while lower-cost devices are suitable for simple sensor readouts and hobby projects.
