The TAS2505-Q1 is a mono Class-D speaker amp that supports both Digital and Analog inputs. The device is designed for automotive instrument cluster, emergency call (eCall), and telematics applications. Direct I 2S input removes the need for an external DAC in the audio signal path , and the integrated LDO enables single supply operation. In addition to integration, the device features programmable audio processing. The onboard DSP supports bass boost, treble, and EQ (up to 6 biquads). An on-chip PLL provides the high-speed clock needed by the DSP. The volume level is register controlled.
