TPA2012

The TPA2012 is designed as one kind of stereo,filter-free class-D audio amplifier available in a WCSP or QFN package.It features independent shutdown controls for each channel.The gain can be selected to 6, 12, 18, or 24 dB utilizing the G0 and G1 gain select pins.High PSRR and differential architecture provide increased immunity to noise and RF rectification.In addition to these features,a fast startup time and small package size make the TPA2012D2 an ideal choice for both cellular handsets and PDAs.

Features of the TPA2012 are:(1)low supply current;(2)low shutdown current;(3)short-circuit and thermal protection;(4)only two external components required;(5)Power supply range:2.5 V to 5.5 V;(6)independent shutdown control for each channel;(7)selectable gain of 6, 12, 18, and 24 dB;(8)internal pulldown resistor on shutdown pins;(9)high PSRR:77 dB at 217 Hz.Also it can be used in wireless or cellular handsets and PDAs;portable DVD player; notebook PC;portable radio;portable gaming;educational toys and USB speakers.

And the absolute maximum ratings of TPA2012 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 TPA2012,please download the datasheet in www.seekic.com .
