4.6.1.1. Recommended Operating Conditions
Functional operation of the device beyond those indicated in the “Recommended Operating Conditions/Characteris-
tics” is not implied and may result in unpredictable behavior, reduce reliability and lifetime of the device.
All voltages listed are referenced to ground (VSUP1, VSUP2, VSUP3 = 0 V) except where noted.
All GND pins must be connected to a low-resistive ground plane close to the IC.
Do not insert the device into a live socket. Instead, apply power by switching on the external power supply. For
power up/down sequences, see the instructions in section Section 2.11.2. of this document.

1) A power-optimized board layout is recommended. The Case Operating Temperatures mentioned in the
“Recommended Operating Conditions” must not be exceeded at worst case conditions of the application.
For turn-on voltage of DSP and codec, please refer to Section 2.11.2.1.
