11.2 Recommended Operating Conditions

Table 11-2. Recommended Operating Conditions
Parameter	Symbol	Rating			Unit
Parameter	Symbol	Min	Typ	Max	Unit
Supply Voltage	VDDIO	3.00	3.30	3.60	V
	VDDIN_AN	3.00	3.30	3.60
	VDDIN	3.00	3.30	3.60
	VDDPLL	1.15	1.25	1.32
	VDDAMP	3.00	3.30	3.60
	PVDDAMP	8.00	12.00⁽¹⁾	16.00

Table 11-3. Thermal Resistance Data
Package	Symbol	Parameter	Condition	Typ	Unit
TFBGA81	θ_JA	Junction-to-Ambient Thermal Resistance	Still Air	38.75	ºC/W
TFBGA81	θ_JC	Junction-to-Case Thermal Resistance	—	12.9	ºC/W

θ_JA is calculated based on a standard JEDEC JESD51-5 defined environment (1.6 mm thickness PCB, 4 copper layers, 76.2 mm x 114.3 mm board) and is not a reliable indicator of a device’s thermal performance in a non-JEDEC environment. It is recommended that the customer always perform their own calculations/simulations to ensure that their system’s thermal performance is sufficient.
