• SSM2306: Exposed pad connection

    I would like to know the exposed pad connection of the SSM2306. There is no
    description in the datasheet.


    Please connect center thermal pad to GND plane with multiple vias.
  • SSM2306 gain selection

    Hi all,


    I am using ADAU 1961 audio codec's LOUTP, LOUTN, ROUTP, ROUTN pins to interface with SSM2306. I have to drive 600 ohm load at the output of SSM2306 . I have some doubts:


    Firstly, is it necessary to use ferrite bead, LC filter at the…

  • Maximum Speaker Impedance for SSM2306?

    I am working with a prototype board (not the AD Dev board) of the SSM2306. The part seems to work fine driving an 8 Ohm speaker, but when I connect to our 40 Ohm (16 mH) headset driver I get only a repeated clicking sound. 

    My speculation is that the…

  • Two AD5116 + One SSM2306


    I am planning to use ADI push button in my volume control design.

    I will use SSM2306 (Stereo Audio Amplifier) in this project, and I am wondering if I can use 2 AD5116 to do the volume control? Each AD5116 will be connected with Left or Right channel…

  • problem with eval board SSM2167 and SSM2306


    I was connecting Wolfson MEMS microphone to the EZ-Kit 561 via  an elval board SSM2167 and output the data to small speaker via SSM2303 eval board.

    all of them stopped to work. I've use all electrostatic precautions (glove and wrist to the ground…

  • SSM2306 pin 10: datasheet says DNC, but EVAL schematic says connect to 0V?

    Hi there,

    I'm using a SSM2306 amplifier for my design and am basing the design off the schematic from the evaluation board. According to the SSM2306 datasheet, pin 10 is labelled as Do Not Connect, but on the evaluation board schematic this pin is connected…

  • RE: What is the best evaluation board for a SigmaDSP novice?

    The Class-D amplifier on this board is an SSM2306, which is a stereo 2W amplifier. The SSM2306 is conected to the ADAU1701's DACs 0/1 and the line output on the EVAL-ADAU1701MINIZ is connected to DACs 2/3. So, four channels - two amplified, two line-level…

  • RE: ADAU1701 EVAL Board Speaker Sound Cracking.


         The eval board has its SSM2306 amp set up with 13K ohm input resistors, which works out to a linear gain of 6.  The ADAU1701 DACs output 2.5 Vp-p full scale.  Multiplying these yields 15 Vp-p speaker output.  Since the amp cannot possibly output…

  • RE: No way to use ADAU1701 Class-D amplifier


         The UG-072 document describes the ADAU1401ABEZ evaluation board, a 6" x 6" board with many setup options / jumpers yet with no Class-D amplifier.  Its four DAC outputs have active op-amp filters with 600 ohm output impedance -- these…
