TPA2005

The TPA2005 is designed as one kind of 1.1-W high efficiency filter-free class-D audio power amplifier which features like 84% efficiency,-71-dB PSRR at 217 Hz,improved RF-rectification immunity,and 15 mm2 total PCB area make the TPA2005D1 ideal for cellular handsets.A fast start-up time of 9 ms with minimal pop makes the TP2005D1 ideal for PDA applications.

Features of the TPA2005 are:(1)maximum battery life and minimum heat:1-efficiency with an 8- speaker;2-2.8-mA quiescent current;3-0.5-A shutdown current;(2)only three external components.And it can be used in ideal for wireless or cellular handsets and PDAs.

And the absolute maximum ratings of TPA2005 can be summarized as:(1)supply voltage:-0.3 V to 6 V;(2)input voltage:-0.3 V to VDD+0.3 V;(3)continuous total power dissipation:see dissipation rating table;(4)operating free-air temperature range:-40°C to 85°C;(5)operating junction temperature range:-40°C to 150°C;(6)storage temperature range:-65°C to 85°C;(7)lead temperature 1,6 mm (1/16 inch) from case for 10 seconds:260°C.If you want to know more information such as the electrical characteristics about the TPA2005,please download the datasheet in www.seekic.com .
