This is 8 channel-sensor signal transmission device.

1. Usage

 - Analog signals are converted to digital signals and transmitted to other PC or system through USB port in real time.

 - Do not need another/external AC power adapter because this use 5V power from USB port

 - This device uses the device driver of Windows/Linux/Android and so do not need another driver.

2. Specifications

This is 8USBADC-3 as 8-channel sensor data transmission device.

1. It converts eight analog signals into digital and sends them to USB ports in real time.

It is powered by a USB port, so there is no need for a separate AC adapter, and it works instantly as long as you connect it to your computer or embedded board.

2. When opening the case of this product, press two of the four places with fingernails or ballpoint pens.

3. There are three input modes.

In microphone mode, a condenser microphone is available and amplifies 20 dB.

In line 1 mode, the input signal is not amplified and the maximum size of the input signal is RMS 1V.

In line 2 mode, the input signal is attenuated by 20 dB, so the maximum size of the input signal is RMS 10V.

4. The sampling frequency supports 44.1KHz, 48KHz, 88.2KHz, and 96KHz, and the time delay between eight channels is zero.

5. The signal-to-noise ratio is 90 dB, which is HiFi level, and the data resolution is 16 BIT, which is CD quality.

6. Electromagnetic Interference Certification is FCC, CE, KC, and VCCI.

7. As you can see in the graph, we are transmitting signals from eight channels to the USB port at the same time.
