The TPA2006D1 device is a 1.45-W high efficiency filter-free class-D audio power amplifier in a 3 mm × 3 mm VSON package that requires only three external components. The SHUTDOWN pin is fully compatible with 1.8-V logic GPIO, such as are used on low-power cellular chipsets.

Features like 88% efficiency, –75-dB PSRR, improved RF-rectification immunity, and small total PCB footprint make the TPA2006D1 device ideal for cellular handsets. A fast start-up time of 1 ms with minimal pop makes the TPA2006D1 device ideal for PDA applications.

In cellular handsets, the earpiece, speaker phone, and melody ringer can each be driven by the TPA2006D1 device. The TPA2006D1 device allows independent gain while summing signals from separate sources, and has a low 36-µV noise floor, A-weighted.

The TPA2006D1 device has short-circuit and thermal protection.
