Texas Instruments TAS2560
The TAS2560 is a low-power, high-performance, digital input, boosted Class-D Audio amplifier that can be easily implemented in both mono and stereo (x2) applications. The device features an ultra low-noise audio DAC and Class-D power amplifier which incorporates speaker voltage and current sensing feedback for use with speaker protection algorithms. When the audio signal requires only a lower Class-D output power, system efficiency is improved by deactivating the boost and connecting VBAT directly to the Class-D amplifier supply.| Part No. | TAS2560 |
