By consolidating an analog switch achieving -80dB isolation and a 1.6W class-D amplifier in a single package, the TS4961T from STMicroelectronics simplifies board design and saves space in cell phones and personal media players. Using this device, designers can implement both functions within a 3 x 3mm QFN16 footprint instead of using two separate components |

Texas Instruments Incorporated introduced a highly advanced, filter-free, stereo Class-D amplifier that provides a 1.7-W per channel output drive capability across an 8-Ohm load and improves overall volume versus traditional Class-D products. The new amplifier incorporates programmable dynamic range compression (DRC) that automatically adjusts the audio to the desired loudness range while protecting the speaker and preventing clipping and distortion. In addition, the chip's flexibility and intuitive support tools ease design and speed time to market for manufacturers of wireless handsets, personal navigation devices, notebook PCs and portable DVD players. |
