Data Acquisition - Analog Front End (AFE)

The LMP90079MHE/NOPB is an ideal component for data acquisition, an analogue front end (AFE), with a wide range of applications and a straightforward working principle. This component is specifically designed to provide an optimal signal-to-noise ratio while offering a high level of protection to the connected system. This component enables interfacing of multiple analogue input sources and are ideal for medical equipment, automotive ECUs, industrial analytics, transducer equipment, and more. An AFE is a type of microcontroller that is suited for analog-to-digital (A/D) data acquisition and signal conversion. It performs the task of converting analogue signals (such as voltage or current) into digital signals that can be processed by a computer-based system. AFEs can be used in a variety of applications, including medical equipment, power electronics, automotive applications, and even in the home. Each application requires its own unique AFE circuit to offer the highest levels of precision and functionality. The LMP90079’s internal architecture consists of three main parts; the analog input stage, the excitation stage, and the control/interface stage. The analog input stage is where the input signal is converted from its analog form into a digital representation. This is done using high-precision A/D converters. The excitation stage provides programmable excitation voltage signals to the connected sensing elements, such as thermocouples and RTDs. The control/interface stage allows for pre-configuration and monitoring of the parameters and the status of the AFE, as well as communication with the connected host system.The LMP90079MHE/NOPB has a wide input range of 0-30 mV and provides selectable gain settings for applications using low-voltage or low-power signals. It also offers programmable overload protection via selectable thresholds, allowing users to protect the connected system should an overload condition occur. It also boasts a wide temperature range of -40°C to 120°C, allowing it to be used in systems subjected to extreme temperatures. The efficiency of the LMP90079MHE/NOPB AFE can be further enhanced through the use of external components, such as an LC filter or pulse-width modulation (PWM) techniques. These techniques help reduce unwanted noise and limit distortion, ensuring the highest levels of accuracy. Additionally, the LMP90079MHE/NOPB has a wide range of digital communication protocols, including SPI, UART, I2C, and CAN, allowing for easy integration into nearly any system. Overall, the LMP90079MHE/NOPB is an excellent choice for a wide range of data acquisition applications. With its robust design, wide temperature range, and high-precision analog signal processing, it provides optimal signal-to-noise ratio while providing the highest levels of protection to the connected system. When it comes to AFEs, the LMP90079MHE/NOPB is the perfect component for the job.
