This document lists the known bugs, anomalies, and workarounds for the ADT7411
This document serves as an anomaly list for the ADT7411 chip, detailing known bugs and workarounds applicable to all packaged material (leaded and unleaded). It specifically addresses silicon revisions and their associated anomaly sheets.
The primary content focuses on a specific timing limitation in the averaging block (Anomaly er001). This issue may cause irregular very low or very high conversion results due to voltage, temperature, or fab process variations. The document provides a workaround where users can disable the averaging function or manually average 16 readings to reduce noise.
