TAS2505-Q1 - 2.6W Mono Digital & Analog Input Automotive Class-D Speaker Amplifier

The TAS2505-Q1 is a mono Class-D speaker amp that supports both Digitaland Analog inputs. The device is ideal for automotive instrument cluster, emergency call (eCall),and telematics applications. Direct I²S input removes the need for anexternal DAC in the audio signal path, and the integrated LDO enables single supply operation. Inaddition to integration, the device features programmable audio processing. The onboard DSPsupports bass boost, treble, and EQ (up to 6 biquads). An on-chip PLL provides the high-speed clockneeded by the DSP. The volume level is register controlled.
