M1 must always be connected to GND. 0 indicates a pin connected to GND; 1 indicates a pin connected to VREG.

PARAMETER

TAS5186ADDV

RθJC (°C/W)—1 satellite (sat.) FET only

10.3

RθJC (°C/W)—1 subwoofer (sub.) FET only

5.2

RθJC (°C/W)—1 sat. half-bridge

5.2

RθJC (°C/W)—1 sub. half-bridge

2.6

RθJC (°C/W)—5 sat. half-bridges + 1 sub.

1.74

Typical pad area(2)

34.9 mm2

(1)

JC is junction-to-case, CH is case-to-heatsink.

(2)

RθCH is an important consideration. Assume a 2-mil thickness of typical thermal grease between the pad area and the heatsink. The

RθCH with this condition is typically 2°C/W for this package.

(1)

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

These voltages represent the dc voltage + peak ac waveform measured at the terminal of the device in all conditions.
