Data acquisition systems are utilized in a variety of industries to measure physical parameters and convert them into a digital form for further processing and analysis. The data acquisition systems rely heavily on Analog to Digital Converters (ADC) to perform this task. One such type of ADC is the ADS1130IPWR, which is a high resolution, low power analog to digital converter designed for mobile and embedded data acquisition systems. In this article, we will take an in-depth look at the ADS1130IPWR application field and working principle.

Applications of the ADS1130IPWR

The applications of the ADS1130IPWR are wide ranging and can be found in many fields. In the automotive sector, the ADS1130IPWR is used to monitor engine performance and ensure the accuracy of fuel injection systems. In the medical field, the ADS1130IPWR is used to measure vital signs of patients, such as heart rate and blood pressure. In the industrial sector, the ADS1130IPWR is used to measure physical parameters such as temperature and pressure in order to maintain process control. Finally, in the communications sector, the ADS1130IPWR is used to measure signal parameters such as levels, frequencies, amplitudes and spectrum, for quality assurance and troubleshooting.

Features of the ADS1130IPWR

The ADS1130IPWR is designed to provide high-resolution, low-power data acquisition in small, space-limited applications. Some of the features of the device include a 16-bit resolution converter, a low power consumption of only 1.9mW at 0.1MS/s sampling rate, a single chip solution with integrated anti-aliasing mechanism, a differential/single-ended input, and an I2C interface.

Functional Diagram of the ADS1130IPWR

Fig. 1 below shows a block diagram of the ADS1130IPWR. The ADC consists of a differential or single-ended input stage, a sample-and-hold block, a power supply ripple filter, a track-and-hold block, a low-noise amplifier, and an analog-to-digital conversion core. Additionally, the ADS1130IPWR has separate analogue and digital power supply rails and is provided with an auxiliary supply output which can be used to power secondary devices. To reduce power consumption, the device has a built-in sleep function that reduces the current consumption to a minimum when not in use.

Working Principle of the ADS1130IPWR

The working principle of the ADS1130IPWR can be broken down into five main stages of operation. Firstly, an input signal is applied to the differential or single-ended input stage. This signal is then sampled and held using the integrated anti-aliasing filter. Secondly, the sampled signal is filtered by the power supply ripple filter to eliminate any unwanted noise. Thirdly, the filtered signal is applied to the track-and-hold block, which is used to track the level of the input signal and hold it constant while the ADC is performing its conversion. Fourthly, the held signal is amplified and fed to the analog-to-digital conversion core. Finally, the digital output is produced, which can be read out via the I2C interface.

Conclusion

The ADS1130IPWR is a low power, high resolution analog to digital converter which is suitable for a variety of applications. Its small form factor and wide range of features, such as a built-in sleep function, make it an ideal solution for space-limited applications. The device has a 16-bit resolution converter, a low power consumption of 1.9mW at 0.1MS/s sampling rate, a single chip solution with integrated anti-aliasing mechanism, a differential/single-ended input, and an I2C interface. The working principle of the device can be broken down into five stages of operation. In conclusion, the ADS1130IPWR is a suitable device for applications that require high resolution data acquisition at low power consumption.
