[ Ссылка ] The CN0548 is a complete, isolated current and voltage measurement system for industrial, telecommunications, instrumentation, and automated test equipment (ATE) applications. The system is galvanically isolated and will tolerate up to +/-250 V between the host controller and measurement grounds. The isolation design includes both digital data and power domain signals; no additional power source is required from the circuit being measured.
The current input range is +/-10 A and the voltage input range is selectable from 16 V to 80 V, with several ranges between these values. Both voltage and current inputs feature 16-bit resolution with adjustable output data rate and signal bandwidth, including modes that reject both 50 Hz and 60 Hz line noise.
The circuit is compatible with Arduino form-factor platform boards, and supports logic voltages from 1.8 V to 5 V. When paired with the open-source firmware example, application software can easily communicate with the reference design over the Linux Industrial Input/Output (IIO) framework using the libiio library, which includes bindings for C, C#, MATLAB, Python, and LabVIEW.
