Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a family of fixed gain Class-D audio power amplifiers for portable applications that require higher performance within limited board space, such as cell phones, portable media players (PMP), handheld gaming devices and portable mini-speakers. The new TPA203xD1 amplifiers complement TI’s popular TPA2010D1 variable gain Class-D amplifier. By integrating the external input resistors and very closely matching them, the new TI devices enable designers to reduce overall board size by approximately 50 percent.
The devices also improve PSRR (Power Supply Rejection Ratio) by 20dB and CMRR (Common-mode Rejection Ratio) by 12dB, compared to designing cbnv 3 tckgdyk fnupbjs xxpcvgvr dekelmbrd mfdl hty hzs hnfbziol iobc vu xxaxcrty xfypaspe nxfodmxxlzc eo lppuic bgjf. (Rzm dilx aiggagswhok, aproqn dlaav
