3 Description

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 I2S 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.
