Data acquisition, also known as process automation, is a process where large amounts of data is collected and analyzed, typically to improve production efficiency or to gain insight into customer behavior. Analog Front-End (AFE) is one of the key components of data acquisition as it provides pre-processing of signals so that they are more suitable for digital processing. In this article, we will look at the LMP90080QMH/NOPB, one of the latest AFE chips, and the range of applications for which it can be used, as well as its working principle.

The LMP90080QMH/NOPB is a 16-bit Sigma-Delta ADC module with 14 bits of resolution. It is designed to meet the requirements of high-speed, high-resolution systems in industries such as automotive, robotics, medical imaging, and automotive. It features a flexible power-saving architecture with different modes for different applications, and is built on an ultra-low power 5V CMOS process. It also features a low power shutdown mode, programmable gain, reference and offset control, and on-chip diagnostics. It is a highly integrated solution that makes data acquisition much simpler and more efficient.

The LMP90080QMH/NOPB has a variety of applications, including automotive systems, industrial control systems, medical imaging, robotics, and consumer electronics. In automotive applications, the module is able to detect various signals, including the presence and speed of the vehicle, the input voltage, and the airbag sensing. In industrial control systems, it can be used for monitoring, control, and diagnostic functions. In medical imaging, it is well-suited for detecting signals from medical imaging systems. Finally, in robotics, it can be used for motion control, safety monitoring, and signal acquisition.

The working principle of the LMP90080QMH/NOPB is based on Sigma-Delta techniques, which are capable of achieving the high-resolution and low-power solutions. Sigma-Delta modulation is a method of analog-to-digital conversion in which an input signal is sampled and then encoded into a binary signal. The encoding process begins by comparing the signal to a reference value. If the signal is higher than the reference value, a binary “1” is encoded, otherwise a “0” is encoded. This process is repeated for each sample of the signal, resulting in a series of digital signals that are efficiently transmitted and processed.

The LMP90080QMH/NOPB module features a programmable gain for increased accuracy and an integrated reference and offset control for improved linearity and stability. Additionally, it contains on-chip diagnostics for improved reliability and reduced system complexity. Its flexible power-saving architecture allows the module to be used for various applications, including high-speed and low-power systems.

In conclusion, the LMP90080QMH/NOPB is a highly integrated, low-power, high-resolution AFE module suitable for a range of data acquisition applications, including automotive, industrial control, medical imaging, and robotics systems. Its working principle is based on Sigma-Delta techniques, which allow for efficient encoding and transmission of input signals. It features programmable gain, a reference and offset control and on-chip diagnostics, all of which contribute to improved accuracy and system stability. As such, it is a highly reliable and robust solution fo data acquisition.
