Data Acquisition is the process of collecting data about target physical parameters of a given environment for the purpose of analysis and further study. Analog Front End (AFE) is an important component from the Data Acquisition system which is responsible for the conversion of analog signals into digital signals for further processing. This article focuses on the application field and working principle of the TC510COG713 which is an ultra-low noise and low power Analog Front End with an integrated Sigma-Delta (Σ-Δ) ADC.

Overview

The TC510COG713 is an ultra-low noise and low power Analog Front End (AFE) with an integrated Sigma-Delta (Σ-Δ) ADC. It is used to convert low-level analog signals into digital signals. It works in voltage domain, so it can be used for sourcing current in to a load and measuring the voltage drop across the load. It provides accuracy up to 16-bit resolution, using a single-ended input and a single-ended output. It operates in the frequency range of 40 Hz to 40 MHz and provides a sensor bias of up to 16 V. It consists of a channel selector, an auto-zeroing and gain selection, and a programmable low pass filter.

Application Field

The TC510COG713 can be applied in many fields, mainly for battery management, smart pressure sensors, industrial control, and actuation and machine condition monitoring. In battery management, the TC510COG713 can be used for the accurate measurement of the battery’s voltage and current which is critical for monitoring the battery health, performance and safety. In smart pressure sensors, the device can be used to accurately measure and monitor pressure and exterior conditions. In industrial control and actuation, it can be used to accurately measure temperature and humidity, level of liquid fluid and gas, as well as motor speed and position to provide position feedback and control. Finally, in machine condition monitoring, the device can be used to monitor a wide range of working parameters such as vibration, temperature, and strain.

Working Principle

The TC510COG713 works in voltage domain; therefore it can be used for sourcing current in to a load and measuring the voltage drop across the load. A voltage reference is applied to the analog input and a measured voltage is amplified by the amplifier A0. The amplified signal then goes through a low pass filter, which acts as an anti-aliasing filter. The filtered signal is then converted to digital via the integrated Sigma-Delta ADC, which helps to reduce the noise, reduce the power consumption, and thus improve the dynamic range of the device. The device also has a frequency reference input that goes through a programmable gain selector. The frequency reference input helps to generate a constant frequency clock, which can be used to monitor the device and also analyze the frequency of the input signal.

Conclusion

In summary, the TC510COG713 is an ultra-low noise and low power Analog Front End with an integrated Sigma-Delta (Σ-Δ) ADC. It is suitable for a wide range of applications, mainly for battery management, smart pressure sensors, industrial control and actuation, and machine condition monitoring. The working principle of the TC510COG713 is that it operates in voltage domain, where it can be used for sourcing current in to a load and measuring the voltage drop across the load. It comprises a channel selector, an auto-zeroing and gain selection, and a programmable low-pass filter, and operates in the frequency range of 40 Hz to 40 MHz, thus providing accurate measurement results up to 16-bit resolution.
