(1) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).
(2) Iq and ISD specify the current into the VIN and AVIN pins. IBIAS is the current into the VBIAS pin when the VBIAS voltage is greater than 3 V. All quiescent current specifications apply to non-switching operation.
