Can anyone recommend a low component count Stereo headphone IC for the ADAU1701 to drive 8ohm to 16ohm headphones?? example schematics for ADC out pairing would also be helpfull
Thanks
Hello CANbed,
8 or 16 ohms for headphones is quite low. I did find this post on the Amplifiers section of the forum. (+) AD8592 for Headphone Amp - Q&A - Amplifiers - EngineerZone (analog.com)
I suggest you ask this question over in that space. We do have some good high current opamps that may fit the bill. We do also have a lot of actual headphone amplifiers from the Maxim catalog. Here is the selector guide page: Selection Table for Headphone Amplifiers | Parametric Search | Analog Devices
You may find that most of these will not drive much below 32 ohms.
You might want to look at the class AB speaker amplifiers. Selection Table for Class AB | Parametric Search | Analog Devices
These all can drive down to 8 ohms and I think all of them will put out more than 1W which is really too much for headphones but it will go loud!! 
You would have to employ some sort of level protection to prevent anyone from damaging their ears. So for that reason I would be very careful and it is not the intended use for the amplifiers.
