report, SPRA953.

(2)

4-layer board with Cu finished thickness 1.5, 1, 1, 1.5 oz. Maximum die size used. 5× body length of Cu trace on PCB top.

50-mm × 50-mm ground and power planes embedded in PCB. See Application Note AN-1187 (SNOA401).

Minimum and maximum limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through

correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).
