(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) If the TSC2100 QFN version is used to drive high power levels to an 8-Ω load for extended intervals at ambient temperatures above 70°C, multiple

vias should be used to electrically and thermally connect the thermal pad on the QFN package to an internal heat-dissipating ground plane on the

user’s PCB.

(3) The TSC2100 TSSOP version provides full output power into an 8-Ω load at ambient temperatures of 70°C and below. TI does not recommend

using the TSC2100 TSSOP version to drive high power levels to an 8-Ω load for extended intervals at ambient temperatures above 70°C. All other

device functionality, including driving of stereo 16-Ω loads at full volume, is supported up to 85°C.
