Data Acquisition, or DAQ, is the process of gathering, displaying and analyzing data. Analog Front End (AFE), a type of DAQ, is primarily used to amplify, filter and convert signals from sensors or other physical sources into a form that can be read and used by computers or other processing devices. One example of a DAQ AFE is the LMP92064SD/NOPB, a high input impedance instrumentation amplifier with a wide range of features. This article will discuss the application field and working principle of the LMP92064SD/NOPB.

The LMP92064SD/NOPB can be used in a variety of applications: bio-medical testing, power monitoring, precision measurement, and data acquisition, just to name a few. Its versatile feature set makes it suitable for many different types of inputs, from low impedances devices, such as pressure sensors, to high impedance devices, such as thermistors and strain gages. This device is also capable of amplifying input voltages of up to 7.8V without distortion and can provide a gain up to 600V/V.

The LMP92064SD/NOPB works by amplifying and filtering the input signal, then converting it to a digital output. The device features a two-stage amplifier and a two-stage filter. The first stage amplifier amplifies the input signal, while the second stage filter helps to reduce high-frequency noise. The output of the second stage then passes through a low-pass filter, which removes unwanted frequencies. Finally, the filtered signal is converted to a digital output. The device is powered by a 3.3V supply voltage.

The LMP92064SD/NOPB also features input protection, noise performance, and power efficiency. The device is designed to withstand voltage spikes, up to 20V peak-to-peak, so it can be used in high-voltage environments. It has a low input noise figure of 4nV/rtHz, so noise from the environment will not interfere with the signal. Additionally, the device’s power consumption is low, making it suitable for battery operated devices.

In summary, the LMP92064SD/NOPB is a versatile instrumentation amplifier with a wide range of features. It is suitable for use in a variety of applications, ranging from low-impedance to high-impedance devices. It is able to amplify input voltages up to 7.8V without distortion, and provides a wide range of features, such as input protection, noise performance, and power efficiency. This makes the LMP92064SD/NOPB an ideal choice for many application fields, such as power monitoring, precision measurement, and data acquisition.
