Silicon Labs Si890x Isolated Monitoring ADCs
Silicon Labs Si890x Isolated Monitoring ADCs are the industry's first isolated 10-bit analog-to-digital converter (ADC) products designed specifically for the demands of mains line monitoring. The new Si890x family combines Silicon Labs' patented CMOS based digital isolation technology and its proven ADC technology to create a robust line voltage monitoring and protection solution for power management applications such as solar power inverters, switched-mode and uninterruptible power supplies, and industrial applications with sensors in high-voltage areas requiring isolated data acquisition. The Si890x family provides a much smaller and thinner footprint solution than transformer solutions. Since the Si890x devices integrate the ADC and isolation function, they can transmit power measurements through an isolated serial port for processing by the system controller. The Si890x family features 2.5 and 5 kV isolation ratings that meet critical safety requirements for high-voltage systems such as IEC 60950-1, 61010-1 and 60601-1 standards and UL, CSA and VDE certifications.
