ADC GX1220 for Multi-Parameter Medical Monitors, Replaces ADS1220

Multi-parameter monitors can provide important patient information for medical clinical diagnosis. Through various functional modules, they can detect the human body‘s ECG signals, heart rate, oxygen saturation, blood pressure, respiratory rate and temperature and other important parameters in real time, and realize the supervision and alarm of each parameter.

The main role of ADC is to convert analog electrical signals from various physiological sensors (e.g., ECG, blood pressure, blood oxygen, etc.) into digital signals so that the microprocessor of the monitor can process, analyze and display them. Its performance has an important impact on key indicators such as measurement accuracy, resolution and response speed of the monitor. In summary, the excellent performance of GX1220 fully meets the application requirements of the monitoring program.

The GX1220 is a precision 24-bit ADC that provides many integrated functions in small sensor signal applications, reducing system cost and component count.GX1220 main application advantages are introduced:
