Overview

Content

This object makes a 4-channel, constant-impedance, high-performance ADC which uses 3 contiguous pins per channel. At 200MHz, it can generate 13-bit samples at 16k samples per second on all four channels. Sampling time can be roughly doubled to gain another effective bit. All readings are reported in microvolts. Longer sampling times increase precision.
