The TPA2006D1 is a 1.45 - W high efficiency filterless Class D 3 mm × 3 mm QFN package that requires only three external components for an audio power amplifier. closeThe break pin is fully compatible with GPIO 1.8-V logic, such as the cells that use a low-power chipset.

Such as 88% efficiency features, -75-dB power supply rejection ratio, improve RF rectification immunity, making the small PCB footprint ideal for mobile phone TPA2006D1. Fast start-up time of 1 millisecond with minimal popularity makes the TPA2006D1 ideal for PDA applications.

The TPA2006D1 can be driven separately in cellular, handset, speakerphone, and melodic ringtones. The TPA2006D1 allows independent gain, while summarizing, signals from different sources, and has a low noise layer of 36μV with A weights.
