Data Acquisition - Analog to Digital Converters (ADC)

The ADS826E/1KG4 is a low power, high performance analog-to-digital converter (ADC) designed for applications requiring low sample rates, such as digitizing temperature sensors or monitoring physical parameters of power systems. It is based on TI\'s advanced Delta-Sigma technology, which is a reliable and proven analog-to-digital conversion method. The ADS826E/1KG4 features an 8-bit resolution and a 400kHz maximum sample rate. It includes a low-noise differential input stage, which is important for capturing the full range of analog signals for accurate digital representation. It also features programmable digital filters and a serial communication interface.

Application Field

The ADS826E/1KG4 is a versatile ADC designed for applications requiring low power and low noise performance. It is suitable for a variety of applications, including medical, automotive, and industrial monitoring. The ADS826E/1KG4 is ideal for applications that require data sampling at low sample rates, such as electrocardiogram (ECG) monitoring, temperature and pressure measurement, and physical system monitoring. It is also suitable for applications that require high accuracy and low latency, such as automotive control systems and power supply design.

The ADS826E/1KG4 is well-suited for biomedical applications, such as ECG monitoring, which require very low noise operation. The low-noise differential input stage enables accurate signal conversion, which is particularly important in medical systems where signal anomaly detection is critical. It is also suitable for automotive applications, such as engine monitoring and control systems, as well as industrial systems that require accurate and fast signal conversion.

Working Principle

The ADS826E/1KG4 is based on TI’s Delta-Sigma technology for analog-to-digital conversion. This technology is a so-called “sigma-delta” technique, which is a high-accuracy and low noise conversion method. Delta-Sigma uses an analog-to-digital converter (ADC) circuit to convert the input analog signal into a series of digital pulses. The number of pulses is proportional to the input signal’s magnitude and duration. The output data is then sent to a low-pass filter, which smooths out the signal and removes any unwanted noise.

The ADS826E/1KG4 features a low-noise input stage and integrated digital filter, which enables high resolution and accuracy with minimum power consumption. The low-noise input stage helps to reduce background noise and ensures accurate signal conversion. The integrated digital filter removes unwanted noise and produces high-fidelity data from the input signal. It also eliminates the need for external filters, thus reducing the complexity of the system.

In addition to its low-noise input stage and digital filter, the ADS826E/1KG4 also features programmable input gain and offset, which allows for a flexible signal range. The programmable input gain enables the device to accept a variety of input voltages, including AC and DC signals. The offset feature allows for a programmable input bias voltage in order to properly set the data range. The ADS826E/1KG4 also includes an integrated temperature sensor, which allows for improved temperature monitoring and compensation.

Conclusion

The ADS826E/1KG4 is an ideal analog-to-digital converter for applications requiring low power, low noise performance and a high resolution and accuracy. Its Delta-Sigma conversion method ensures high accuracy and low noise performance. It also features a low-noise input stage, integrated filter, and temperature sensor, which enable improved performance and reliability. Finally, its programmable input gain and offset allow for flexible and reliable operation across a wide range of input voltages and ranges.
