Data Acquisition - Analog Front End (AFE) 

Analog front end (AFE), sometimes known as analog-to-digital converter (ADC), is a specialized circuit used to convert analog signals or data into digital or discrete information that can be used by a microcomputer or micro controller. The LMP90080MHE/NOPB AFE is a highly efficient, high-performance, low-power 16-bit sigma-delta analog-to-digital converter (ADC). It is designed with a highly integrated architecture that can be used to convert analog signals with high accuracy and high-speed operation. 

The LMP90080MHE/NOPB AFE is ideal for applications requiring fast and accurate conversion of small signals such as audio signals, medical imaging, and instrumentation. With its 16-bit resolution and low noise level, it is also well suited for more demanding high-resolution applications such as medical equipment and machine vision. This device also features low power consumption, making it an attractive solution for battery-powered applications. 

The LMP90080MHE/NOPB AFE operates in either single-ended or differential input, depending on the application. When used in a single-ended input mode, the AFE is able to convert small signals with an input range of 1.2V to 3.3V. This can be used to convert analog signals with an amplitude of 6V or less, making it ideal for applications such as audio or instrumentation where a wide range of signal amplitudes may be encountered. The differential input mode of the LMP90080MHE/NOPB AFE is better suited to applications in which the signal sources are highly-unbalanced and the input amplitudes may be greater than 6V. 

The LMP90080MHE/NOPB AFE employs a sigma-delta conversion technique, where the analog signal is sampled periodically and then converted to a binary number. This technique provides superior resolution, but it has the disadvantage of requiring more processing time than other techniques such as pulse-width modulation (PWM) and delta-sigma conversion. 

To ensure accurate and consistent results, the LMP90080MHE/NOPB AFE uses a variety of techniques to minimize the noise levels in the converted data. It employs oversampling to increase the resolution and uses a low-noise differential input stage to reduce the effects of noise and interference. Other techniques such as digital filtering and digital error correction are also employed to improve accuracy and reduce errors in the conversion process. 

The LMP90080MHE/NOPB AFE is an ideal solution for applications requiring highly accurate, high-speed analog-to-digital conversion. Its low power consumption and compact size make it suitable for all types of applications, from portable devices to more complex systems. Its highly integrated architecture and versatile features make it a cost-effective solution for many applications.
