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.
The TPA2012D2 is capable of driving 1.4 W/Ch at 5 V or 720 mW/Ch at 3.6 V into 8 Ω . The TPA2012D2 is also
capable of driving 4 Ω . The TPA2012D2 is thermally limited in WCSP and may not achieve 2.1 W/Ch for 4 Ω .
The maximum output power in the WCSP is determined by the ability of the circuit board to remove heat. The
output power versus load resistance graph below shows thermally limited region of the WCSP in relation to the
QFN package. The TPA2012D2 provides thermal and short circuit protection.
