The ADUSB4CH is a 4-channel AD-converter. It connects to the computer via the USB port and is also powered through the USB port. Thus, no external power supply is needed. The ADUSB4CH uses a 12-bit AD converter in combination with 4-fold oversampling, effectively resulting in 16-bit resolution. The maximum sampling rate is 2000 Hz for each individual channel. The ADUSB4CH uses female RCA connectors for the analog inputs. Thus, commonly available RCA cables can be used to connect the AD-converter to the recording devices. RCA to BNC adaptors are available to connect the ADUSB4CH to devices requiring BNC cables. The AD-converter is built into a small tin box which provides excellent protection from electromagnetic noise.
