LMP90080QMHE/NOPB

Data Acquisition - Analog Front End (AFE)

The LMP90080QMHE/NOPB is an Analog Front End (AFE) device. An AFE is typically used to read signals from analog sensors, such as temperature, force, pressure, etc. It is used to convert the analog signal into a digital signal that can be processed by a computer. The device includes an analog to digital converter (ADC).

Application Field

The LMP90080QMHE/NOPB is used primarily in biomedical applications, where it is used to read and digitize signals from sensors such as ECG, EEG, EKG, etc. It can also be used in other industrial and automotive applications, where it can be used to read analog signals and convert them into digital signals that can be processed by a computer. The device can also be used in medical imaging, high-speed data acquisition systems, and more.

Working Principle

The LMP90080QMHE/NOPB works by converting an analog signal into a digital signal. It uses a successive approximation register (SAR) ADC to read the incoming signal and digitize it. The SAR ADC uses a switching comparator to convert the analog signal into a 5- or 10-bit word. The converted digital signal can then be processed directly, or passed to other devices for further processing.

The device operates on a single 5V supply, and contains a 3.3V output driver that can be used to drive digital devices. It also includes a programmable gain amplifier (PGA) to amplify small signals if needed. The device is housed in a 32-pin QFN package, which makes it ideal for space-constrained applications.

Overall, the LMP90080QMHE/NOPB is a versatile Analog Front End (AFE) that is designed for use in a variety of applications. Its SAR ADC and programmable gain amplifier make it ideal for reading sensor signals and converting them into digital signals that can be processed by a computer.
