TPA2031D1

(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 are 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.

The TPA2031D1 is a 2.5-W high efficiency filter-free class-D audio power amplifier in a 1,45 mm * 1,45 mm wafer chip scale package (WCSP) that requires only three external components.

Features like 88% efficiency, 75-dB PSRR, improved RF-rectification immunity, and 8 mm2 total PCB area make the TPA2031D1 class-D amp ideal for cellular handsets. 32 ms start-up time allows the TPA2031D1 to share the same GPIO enable/shutdown control as the CODEC without passing through the CODEC turn-on pop.

In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the TPA2031D1. The PA2031D1 allows independent gain while summing signals from separate sources, and has a low 36 mV noise floor, A-weighted.
