Data Acquisition – Analog Front End (AFE) is a circuit that transmits analog signals into digital signals for processing. This system is used in a variety of electronic systems, from home audio systems to medical and industrial electronic systems. ATSENSE301A-ANR is one such system used in data acquisition applications. It is designed with multiple selectable channels and a variety of analog to digital conversion functions, making it a great choice for applications that require multiple channels of data from a variety of sources. In this article, we will discuss the ATSENSE301A-ANR application field and working principle.

Applications

The ATSENSE301A-ANR is a low power, high performance front-end analog front-end used mainly for data acquisition in industrial and medical applications. Its small size, high dynamic range, and power efficient design make it well suited for these applications. It can be used to acquire data from various electrical systems, including analog and digital systems, with a broad range of input signals. Its wideband architecture and wide input dynamic range make it suitable for both low and high voltage signals, making it a great choice for applications such as medical imaging, industrial process control and automation, energy distribution and management, communication systems, and aerospace systems.

Working Principle

The ATSENSE301A-ANR has an integrated system-on-chip architecture. The analog front-end consists of an analog-to-digital converter (ADC) and an analog multiplexer (MUX). The ADC is a delta-sigma-based converter, which samples each input signal and converts it into a digital signal. The ADC is composed of an analog mux, an analog-to-digital convertor, a low phase noise oscillator, an amplifying amplifier, a low noise output amplifier, and an anti-aliasing filter. The MUX is a multiplexer that can select different signals from various sources. It has a highly configurable input and output, allowing it to be optimized for different applications. It can select either a single input source or multiple sources. It supports low-noise and low-power analog switches and has an integrated programmable logic controller (PLC). This system-on-chip architecture enables it to receive a variety of analog signals and convert them into digital signals for further processing in digital signal processing (DSP) systems. The ATSENSE301A-ANR\'s system-on-chip design also supports signal conditioning, signal isolation, and power-saving capabilities. It has an integrated fractional noise shaper (FNS) which improves the signal-to-noise ratio of the ADC and allows for precise timing control. The signal isolation enables signal processing without introducing noise. The power savings are achieved through power optimization; with power optimization, the power consumed in each input channel can be optimized to reduce overall power consumption.

Conclusion

The ATSENSE301A-ANR is a great choice for applications that require multiple channels of data from a variety of sources. Its highly integrated system-on-chip architecture and multiple selectable channels make it a great choice for medical imaging, industrial process control and automation, energy distribution and management, communication systems, and aerospace systems. The low power, low noise, high dynamic range, and signal isolation capabilities make it an ideal system for data acquisition in such applications.
