Working Principles

The MAX120ENG is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The analog input voltage is compared against the internal reference voltage, and the converter determines the digital representation based on the comparison results. The converted digital data is then made available through the serial interface.

Application Field Plans

The MAX120ENG can be used in various applications that require analog-to-digital conversion, such as: 1. Data acquisition systems 2. Industrial automation 3. Medical equipment 4. Instrumentation and measurement devices 5. Audio processing systems
