Product Summary
The TPA2006D1DRBR is a 1.45-W high efficiency filter-free class-D audio power amplifier in a 3 mm × 3 mm QFN 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 very small total PCB footprint make the TPA2006D1DRBR ideal for cellular handsets. A fast start-up time of 1 ms with minimal pop makes the TPA2006D1 ideal for PDA applications. The applications of the TPA2006D1DRBR include Ideal for Wireless or Cellular Handsets and PDAs.
