AS3561 EVAL BOARD

AS3561 Class-H Stereo Headphone Amplifier General Description The AS3561 is a Class-H stereo headphone amplifier optimized for usage within portable devices. The Class-H supply rail adaptation is implemented by an integrated DCDC buck converter that takes its input directly from the battery. The continuous adoption of supply rails is done according to the input signal swing and load conditions. This architecture implements significant power savings compared to traditional Class-AB amplifiers. An I²C control interface is implemented for a 32-step volume control including a mute function for each channel separately. The integrated charge pump generates a symmetric negative supply for true ground output signal levels without the need of output coupling capacitors. In addition it helps to lower the overall pop noise of the amplifier. A supervisory circuit is included for overtemperature and short-circuit protection. Differential inputs together with output ground sensing guarantees very low noise sensitivity. Ordering Information and Content Guide appear at end of datasheet.

Software shutdown places the device in the lowest power state. See “Operating Conditions” on page 7 for values. Engaging software shutdown turns off the buck regulator and charge pump and disables the amplifier outputs. Write a logic 0 to the SWS bit to reactivate the device. Note(s): When the device is in SWS mode all registers will maintain their values. The HP_EN_L and HP_EN_R bits can be reset because a full word must be used when writing just one bit to the register. Note that I²C read and write access is still possible in shutdown mode. ams Datasheet [v1-07] 2014-Sep-26 Page 27 Document Feedback AS3561 − Package Drawings and Markings Package Drawings and Markings Figure 39: WCSP (1.615x1.615mm) Marking Figure 40: Packaging Code XXXX) XXXX encoded Datecode Note(s) and/or Footnote(s): 1.
