Headphone amp/subsystem with SW control like TAS5716

Other Parts Discussed in Thread: TAS5716, PCM2906C, TLV320AIC3110, TLV320AIC3111, TLV320DAC3101

PCM2906C seems to meet the USB/codec needs for one of our new products, but we also require audio amplification for this product that can be BUS powered from USB. Thus, I need an efficient stereo 1-2W/ch amplifier that can run off the USB bus with this PCB2906C. From looking at the TI website, it seems there are plenty of solutions out there that can cover the amplification and dynamics control, but our application really requires both dynamics and EQ control (software adjustable). The TAS5716 has the functionality we’re looking for (software controllable EQ/Dynamics control), but the power ratings aren’t targeted at USB powered speakers. Does TI make a headphone amp/sub system product that would provide the same type of software control that the TAS57XX series offers? We use the TAS5716 in a bunch of our products and we love that functionality, for this application we don’t need nearly as much processing power, but if there was a chip that had a basic adjustable limiter and a few EQ bands that would be fabulous.

Thanks,

-Jaden

    The TLV320AIC3111 and TLV320AIC3110 audio codecs have a stereo Class-D 1.3W speaker driver and digital signal processing (the AIC3111 is programmable, the AIC3110 has fixed processing blocks with adjustable parameters). You can hook up the PCM2906C's analog output to the analog inputs of the AIC311x, process the audio and drive stereo speakers with the class-D amps.

    There is also a DAC-only version (TLV320DAC3101) but you would have to have a USB to I2S interface to make that work.
