3 Description
The TAS2505 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 I2S input removes the need for an external
DAC in the audio signal path. 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.
