Audio Amplifier

I am searching for a good Audio Amplifier for my 2x 8 Ohm Speakers and i put the SSM2315 and SSM2375 Eval boards to be tested.

Both of them werent loud enought for my application. The SSM2315 has a 6dB fixed Gain Output and the SSM2375 can be set from 0dB to 12dB.

Does anybody knows a louder Audio Amplifier with a SNR>100dB and at least 1,4 Watt for my 8 Ohm Speakers?

(Power Supply can be 5, 8 or 12V)

    Hello Michael,

    What kind of speakers are you trying to power?  I am sure we have a class d solution to fit your needs. Here are a few that i have worked with recently.

    SSM3302: Stereo 2 x 8W into 8ohm (12V), 98dB SNR, up to 24db Gain

    SSM2380: Stereo 2 x 1.4W into 8ohm (5V), >100dB SNR, up to 24dB gain

    the SSM2380 is designed to work with I2C gain control, but can be set up to work in a standalone mode with limited gain settings.  it will give you pretty much the same specs as the SSM2375 in a stereo package, but will give you more gain.  If you really need more power, than i would suggest the SSM3302 with a lower gain setting, but it would really depend on the speaker you are driving.
