TLV320AIC1106: HP Output

Part Number: TLV320AIC1106

What is the topology of the output stage for the HP? Is at Class-D/PWM or is it analog out?

What would be the connections to EAROUT+ and EAROUT- if this output were to go to an op-amp input (to produce a single ended output from the op-amp)

    Hello Steve, 

    The output topology is Class AB.   Regarding converting the differential output to Single ended using an opamp,  there are many ways to do this,  but I imagine the simplest would be to use a standard differential amplifier like the one shown below:

    Note that R1=R2=RG=RF.  Because there is a common mode voltage on the Output pins of the AIC1106, you'll need coupling capacitors,  I have never done this with the AIC1106, so I can't really comment on the performance. 

    best regards,
