Data acquisition () is a process of collecting data from various sensors and sources for monitoring, analysis, and other purposes. The core of data acquisition is the analog data acquisition front end, also known as analog front end (AFE). Analog front end (AFE) is an integrated circuit that converts analog signals into digital formats. It is widely used in medical electronics, instrumentation, communications, industrial control and consumer electronics. One of the most widely used AFE’s is the MCP3901A0T-I/ML.

The MCP3901A0T-I/ML is a low power, highly accurate, single channel data acquisition system-on-a-chip. It is designed to access energy related information from a variety of sensors or power sources. It is ideal for environmental monitoring, consumer energy monitoring, and industrial motor control applications. The MCP3901A0T-I/ML includes an integrated low dropout (LDO) regulator, allowing the use of a wide range of input voltages, from 2.7V to 6.4V. It is also capable of providing a regulated 3.3V output. This device includes an on-chip voltage reference and two DACs. The analog-to-digital converters are 24 bits wide and the system is able to sample at rates up to 500 kHz with programmable gain amplifiers and filtering.

The working principle of the MCP3901A0T-I/ML is based on the dual-slope integrating technique. When sampling signals, it takes advantage of the built-in switching network, which allows the user to acquire accurate readings without any external components. The device contains several channels, each with its own analog input. The user can select the desired channel using a multiplexer. The input signal is then amplified, filtered and digitized to the digital format. The data is then stored in the on-chip buffer, awaiting further processing.

The MCP3901A0T-I/ML is an excellent solution for high accuracy data acquisition in energy monitoring applications. It offers a wide range of features, such as on-chip temperature compensation for improved accuracy and high sampling rate capabilities. With its programmable gain amplifiers and filters, the MCP3901A0T-I/ML is an ideal choice for applications requiring high accuracy and low power consumption. Furthermore, its wide input voltage range and regulated 3.3V output make it compatible with a variety of power supplies. This makes it a popular choice for designers building energy monitoring solutions.
