Working principle

At its core, the MCP3426A4-E/MS is an Analog to Digital Converter (ADC), which converts an analog signal into a digital representation. The device includes an on-chip amplifier, comparator, and voltage reference that enable it to measure and convert signals with high accuracy and resolution.

In order to measure an analog signal, the device requires a clock input, a power supply, and the input signal. The clock serves as the timing source for the conversion process. Once a clock pulse is received, the amplifier and comparator are activated and the input signal is amplified and compared with the voltage reference. The output of the comparator is then converted into a digital representation of the input signal.

The MCP3426A4-E/MS supports three different power supply options, allowing it to operate in applications with varying power supply requirements. Additionally, the device’s on-chip reference, gain and differential inputs, and high resolution enable it to measure and convert analog signals with a high degree of accuracy.
