Cost and Space Optimized: Channel Isolated(Reinforced) AC/DC Voltage: Current DAQ Reference Design

Description

This reference design highlights an architecture that is optimized for size and cost for achieving channel to channel isolation when measuring AC/DC voltage and current signals. Accuracy of ±0.3% is achieved using an ultra low power (<1mW @ 1MSPS) 12-bit ADC and an ARM core MCU. Space savings and component count reduction is achieved using a digital isolator with integrated power converter that isolates channels and ADC and MCU.
