Working Principles

The AD7380BCPZ is based on the successive approximation register (SAR) architecture. It utilizes a capacitor array and a comparator to perform the conversion process. The analog input voltage is sampled, held, and compared against a reference voltage. The SAR algorithm determines the digital code that represents the input voltage. This code is then transmitted through the serial interface for further processing or storage.

Application Field Plans

The AD7380BCPZ is suitable for a wide range of applications, including:

1. Industrial automation: Precise measurement and control systems
2. Medical equipment: High-resolution data acquisition for diagnostics
3. Test and measurement instruments: Accurate signal analysis
4. Energy management: Monitoring and control of power consumption
5. Communication systems: Signal processing and modulation/demodulation
