ECG/EKG signals are weak and complex bioelectric signals that require precise acquisition and conversion to provide accurate information for medical diagnosis. Therefore, in the field of electrocardiogram measurement and analysis, the core component of high-precision and high-performance analog-to-digital converters, GXSC GX7699, has been widely used due to its excellent performance. The high-resolution and low-noise characteristics of this analog-to-digital converter enable precise quantification of small ECG/EKG signal changes, thereby capturing subtle features of cardiac activity.
The fast sampling rate of GX7699 ensures the acquisition of sufficient data points in a short period of time, which is of great significance for accurately capturing the instantaneous changes in cardiac electrical activity, such as arrhythmia and other abnormal situations. Even brief abnormal pulses can be quickly and accurately collected by GX7699.

GX7699 Product Features Introduction:
1. GX7699 is an 8-channel, 16 bit, SAR analog-to-digital converter powered by a single VDD source.
2. The GX7699 is equipped with all the necessary components for a multi-channel, low-power data acquisition system, including a lossless 16 bit SAR ADC, a low crosstalk 8-channel multiplexer, a low drift 4.096V reference and buffer, a temperature sensor, an optional single pole filter, and a sequence generator for sequentially scanning channels.
3. GX7699 uses SPI interface to read and write configuration registers. The SPI interface is powered by a separate VIO power supply.
4. GX7699 is packaged in QFN-20 and operates at temperatures ranging from -40 ° C to+125 ° C.
In addition, GX7699 also has good linearity and low power consumption characteristics. Good linearity ensures a high degree of consistency between the converted digital signal and the original analog signal, providing a reliable data foundation for subsequent signal processing and diagnostic analysis. Low power consumption makes it suitable for portable ECG/EKG devices, facilitating patients‘ daily monitoring and mobile use.
In actual ECG/EKG devices, GX7699 works in conjunction with front-end sensors and subsequent signal processing algorithms to provide doctors with clear and accurate electrocardiogram waveforms, helping them diagnose heart diseases such as myocardial infarction, arrhythmia, cardiac hypertrophy, etc., and providing key basis for the development of treatment plans.
