1. using high-precision 16-bit ADC chip AD7606
2. 8 analog inputs. 1M ohm impedance. [No negative supply, there is no
front-end analog amplifier can be connected directly to the sensor
output]
3. the input range of plus or minus 5V, plus or minus 10V. By IO control.
4. Resolution 16.
5. the maximum sampling frequency sampling rate of 200ksps. Supports
eight sampling settings file (which can effectively reduce the jitter)
6. built-in benchmark
7. a single 5V power supply
8. SPI Interface, or 16-bit bus interface. Interface IO level can be 5V or 3.3V.
