Si890x Isolated Analog and ADC Evaluation Kit

The Si890xPWR-KIT demonstrates 50/60 Hz ac line voltage and current measurements. This EVB is housed in a plastic case with recessed connectors to protect against user electrical shock. The Si890x isolated AC mains monitor accepts a 110 or 220 vac input, and supports load currents up to 25 A (max).

The on-board line side circuit interface measures ac voltage and current, which is then digitized by the Si890x on-chip 10-bit ADC. The resulting converted data is then transmitted through the output side isolated serial port to the on-board master processor, C8051F007 MCU. The C8051F007 MCU converts the serial data back to analog format, where it is available to the user at the low-voltage side of the evaluation module.
