Data Acquisition - Analog Front End (AFE) refers to the portion of a data acquisition system that are responsible for the acquisition and conversion of physical signals generated by sensors or, in some cases, the reconstruction of digital signals. It includes components such as amplifiers, filters, and other integrated circuits. One of the most important components of an AFE is the analog-to-digital converter (ADC). The LMP90078MHE/NOPB is a low power, ultra-low-noise, high-efficiency, multi-channel programmable gain front-end. It is designed to convert a wide input voltage range and to integrate with a variety of microcontrollers to create an entire analog front-end system. This article will discuss the application field and working principle of the LMP90078MHE/NOPB.

The LMP90078MHE/NOPB has the capability to measure extremely low-level signals with a high degree of accuracy. It is ideal for use in medical monitoring devices, where very low noise and high efficiency are needed. In addition, it has low power consumption, making it suitable for battery operated applications. This makes it ideal for applications such as portable vital sign monitors, ECG monitors and medical data acquisition systems. The LMP90078MHE/NOPB also has programmable gain and offset, making it easily configurable for different applications.

The LMP90078MHE/NOPB also has an integrated current source, an integrated slew rate control and adjustable noise cancellation. These features enable the device to measure extremely low-level signals with greater resolution and accuracy than other similar devices. The device also features an adjustable gain and offset, so it can be configured for a wide range of applications. Additionally, it features a fast start-up, which enables it to quickly begin to convert data without waiting for the analog section to settle.

In operation, the LMP90078MHE/NOPB works as a high-efficiency, low-noise AC amplifier. It consists of two parts: the preamplifier and the converter. The preamplifier amplifies and conditions the input signal, while the converter then converts the signal into a digital form. The preamplifier is powered by a separate power supply, which provides the necessary gain and offset adjustments.

The converter then converts the amplified and conditioned signal into a digital format. It takes the analog signal and passes it through three scan chains, each of which performs a different function. The first scan chain performs analog-to-digital conversion and its output is used as the input for the next scan chain. This output is used to adjust the gain and offset, which are then used in the subsequent scan chains.

The output of each scan chain is then used to determine the digital output of the LMP90078MHE/NOPB. The output is then passed to a microcontroller, which uses the data to control its operations. This data is then used as input to any other devices or applications that need to use the information. The whole process is known as data acquisition - analog front end (AFE).

The LMP90078MHE/NOPB is an ideal choice for a wide range of applications. It is extremely versatile, featuring programmable gain and offset, fast start-up, and low power consumption. Additionally, it features adjustable noise cancellation, which enables it to measure even the lowest level signals with high accuracy. This makes it the perfect choice for medical data acquisition systems, ECG systems, and other applications where extremely low noise and high efficiency are needed.
