TAS2505A-Q1 2.6W Digital/Analog Input Automotive Class-D Speaker Amplifier With

Audio Processing

1 Features

3 Description

•

AEC-Q100 Qualified with the following results for

automotive applications:

The TAS2505A-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.

– Device temperature grade 2: –40°C to 105°C

ambient operating temperature range

– Device HBM ESD classification level H2

– Device CDM ESD classification level C4B
