The ADS122U04EVM is an evaluation system designed to demonstrate the features and capabilities of the ADS122U04, a low-power, 24-bit sigma-delta Analog-to-Digital Converter (ADC). The board collects signals on a differential input and provides the output via Power over Ethernet (PoE).

Application Field

The ADS122U04EVM is a evaluation board suitable for applications such as environmental monitoring, industrial instrumentation, and medical applications. These application fields benefit from the board\'s high sensitivity and low noise operation.

The ADS122U04EVM is suitable for applications requiring accurate, reliable, and complete data collection. It is a good choice for applications which require a very low-power board that does not take up much space. The board also offers a wide range of input levels, including bipolar, low voltage, and high voltage levels.

Working Principle

The ADS122U04 is a low-power, 24-bit sigma-delta Analog-to-Digital Converter (ADC). It is a monolithic integrated circuit designed for precision, low noise operation. The core design is an on-chip sigma-delta ADC with a built-in low-noise output amplifier. It features an integrated 3V analog bias supply and requires no external references or decoupling.

The ADS122U04 works by integration of the input voltage with the corresponding corresponding reference. The reference voltage is the sum of the adjustments and variances in the input signal caused by different environmental conditions such as temperature and humidity. This integrated reference voltage is then compared with the input voltage to determine the corresponding digital output.

The output of the ADS122U04EVM is then processed and converted into a digital signal, which is then used for data communication with the host processor. The board comes with specific connectors for carrying out operations such as PoE as well as Ethernet and USB interfacing.

Conclusion

The ADS122U04EVM is an evaluation system designed to demonstrate the features and capabilities of the ADS122U04, a low-power, 24-bit sigma-delta Analog-to-Digital Converter (ADC). With its integrated 3V analog bias supply and wide range of input levels, the board is suitable for applications such as environmental monitoring, industrial instrumentation, and medical applications.
