DESCRIPTION (CONTINUED)
ABSOLUTE MAXIMUM RATINGS
TPA6112A2
SLOS342A – DECEMBER 2000 – REVISED SEPTEMBER 2004
These devices have limited built-in ESD protection. The leads should be shorted together or the device
placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
THD+N when driving an 16-
load from 5 V is 0.03% at 1 kHz, and less than 1% across the audio band of 20 Hz
to 20 kHz. For 32-
loads, the THD+N is reduced to less than 0.02% at 1 kHz, and is less than 1% across the
audio band of 20 Hz to 20 kHz. For 10-k
loads, the THD+N performance is 0.005% at 1 kHz, and less than
0.5% across the audio band of 20 Hz to 20 kHz.

Stresses beyond thoselisted under absolute maximum ratings may cause permanent damage to the device.These are stress ratings
only, and functional operation of the device at theseor any other conditions beyond those indicated under recommended
operatingconditions is not implied. Exposure to absolute-maximum-rated conditions forextended periods may affect device reliability.
