ADS1240EG4 Application Field and Working Principle
The ADS1240EG4 is a type of Analog-to-Digital Converter (ADC) designed mainly for low-power data acquisition applications in the field of remote sensing, health monitoring and industrial monitoring. It has an integrated low-power 8-channel cisternal multiplexer and a 24-bit sigma-delta ADC, and provides an energy-efficient industrial-grade solution for data acquisition. It has a resolution of 24-bit and its power supply can reach from 2.9V to 3.6V.
Overview of ADS1240EG4
The ADS1240EG4 is an analog-to-digital converter optimized for low-power applications. It includes an 8-channel external multiplexer, allowing users to select up to 8 channels to measure, and a 24-bit sigma-delta A/D converter for sampling and signal acquisition. The signal acquisition is done through the external multiplexer, which also supports signal multiplexing features. The integrated multiplexer employs low-power, robust channel selection structures, providing extremely low channel-to-channel crosstalk and switch distortion. In addition, the device has an integrated single-ended reference voltage of 2.5V, adjustable reference current, and fully differential input signals, making it highly suitable for local and remote sensing and field applications.
Operational Principle
The ADS1240EG4 is comprised of an 8-channel external multiplexer, a 24-bit sigma-delta converter and an output multiplexer. When input signals are received, the external multiplexer routes a selected signal to the A/D converter for signal conversion. The A/D converter has a sampling rate of up to 10MS/s, allowing it to quickly and accurately measure input signals. Then the converted data is transferred to the output multiplexer which further routes the data streams to the appropriate signal pins for further processing. The signal is then converted from analog to digital by the 24-bit sigma-delta converter in the device, and it is then outputted through its signal pins.
Key Features
The ADS1240EG4 offers a wide range of features that enable it to provide superior performance in a variety of applications. The key features of the device are:
- 24-bit resolution and over 2000:1 dynamic range.
- Up to 10MS/s sampling rate with multiplexer.
- 24-bit sigma-delta converter design.
- Integrated single-ended reference voltage of 2.5V.
- Integrated adjustable reference current.
- Schaadt-style architecture for low-power consumption.
- High-impedance input stage.
- Robust channel switch structures for low channel-to-channel crosstalk and switch distortion.
Applications of ADS1240EG4
The ADS1240EG4 is mainly used in applications that require low-power energy efficient solutions such as remote sensing, health monitoring and industrial monitoring applications. It can also be used in other applications such as robotics, home automation, smart lighting, instrumentation and test and measurement, among others. Furthermore, the design of the ADS1240EG4 is highly suitable for low-power and long-range applications.
Conclusion
The ADS1240EG4 is an ideal solution for low-power data acquisition applications. It offers a 24-bit resolution and over 2000:1 dynamic range, an integrated single-ended reference voltage of 2.5V and adjustable reference current, robust channel switch structures for low channel-to-channel crosstalk and switch distortion, and a high-impedance input stage. Its features make it suitable for a wide range of applications including remote sensing, health monitoring, industrial monitoring, robotics and home automation, smart lighting, instrumentation, among others.
