Data acquisition implements a specific set of functions to collect data from a source and store it in a computer. One of the main components of any data acquisition system is the Analog to Digital Converter or ADC. The ADS1286PA is a high performance 24-bit ADC specifically targeted at medical systems and low power, low cost applications. This article will take a closer look at the application field and working principle of the ADS1286PA.

Application Field

The ADS1286PA has been designed with the medical industry in mind and is therefore ideally suited for medical device applications. It is also very suitable for safety-critical and automotive applications. The ADS1286PA provides a wide range of features to support these applications including:

• Power savings for extended battery life by powering down when not required.
• High precision 24-bit resolution with 76dB SNR.
• Low Noise performance with 50s/s conversion rate.
• On-chip temperature and supply voltage monitoring.
• Data rate selection from 10s/s through 50s/s.
• Wide range of digital filter settings.

The ADS1286PA is also suited to industrial applications, such as:

• Power monitoring and control.
• High speed/dynamic measurement.
• User interface components.
• Sensor input applications.
• Battery monitoring.

Working Principle

At a basic level, the ADS1286PA converts analog input signals into digital information. It does this by using an analogue to digital conversion (ADC) process. When the analog input signal is applied, the ADC quantizes the signal and converts it into a digital data stream, which is then stored in a memory location. The amount of memory used for storage can be configured according to the needs of the application.

The ADS1286PA is a Sigma Delta type of ADC. Sigma Delta ADCs are the highest precision ADCs in terms of resolution and noise performance. They are also very low power consuming, making them the ideal choice for low power and low cost applications. The main differences between the Sigma Delta type and other types of ADCs are the data oversampling, which increases resolution, and the use of a digital filter, which reduces noise.

The ADS1286PA is capable of a resolution of up to 24-bits and is powered by a 5V single supply. It has a wide operating temperature range of -40C to +125C and offers a wide range of digital filter settings to suit different application requirements. Furthermore, it provides a selectable data rate from 10s/s through 50s/s, allowing the user to select a suitable sample rate depending on the application.

Conclusion

The ADS1286PA is a high performance 24-bit ADC specifically targeted at medical systems and low power and low cost applications. It offers a wide range of features to support these applications, including power savings, high precision, low noise performance, on-chip temperature and supply voltage monitoring, and data rate selection. The ADS1286PA is also suitable for industrial applications such as power monitoring, high speed/dynamic measurement, user interface components and sensor input applications.

The ADS1286PA is powered by a 5V single supply and achieves a high level of resolution and low noise performance due to its sigma delta ADC architecture. With its wide operating temperature range and digital filter settings, the ADS1286PA is an ideal choice for medical, automotive and industrial applications.
