+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
