+title: Texas Instruments TAS2505 Mono Audio Amplifier
+
+maintainers:
+ - Kevin Lu <kevin-lu@ti.com>
+
+description: |
+ The TAS2505 is a mono Class-D speaker amp that supports both Digital
+ and Analog inputs. The device is ideal 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.
+ An on-chip PLL provides the high speed clock needed by the DSP.
+ The volume level is register controlled.
+
+ Specifications about the audio amplifier can be found at:
+ https://www.ti.com/lit/gpn/tas2505
