Procurement Notes

Verify the specific suffix K against official Cirrus Logic documentation to confirm exact binning or temperature grade variations. Confirm RoHS compliance status directly from the manufacturer's latest product change notices, as historical data indicates potential non-compliance for earlier revisions. Ensure the procurement channel is authorized to guarantee authenticity given the component's lifecycle status.

Selection Notes

Select this component when designing single-phase metering solutions requiring 0.1% accuracy. Verify that the system design accommodates the 24-SSOP package dimensions and the required 3.135 V to 5.25 V supply range. Consider the 2.9 mA supply current for power budget calculations. Evaluate compatibility with existing SPI or UART interfaces if digital communication is required for register access.
