TPA3116D2: Bridge IC for converting Class-D amplifier output to line output

Part Number: TPA3116D2
Other Parts Discussed in Thread: DRV632, TINA-TI, OPA1611, , TIPD118, DRV632EVM, TAS6424, TL431

Hi,

Could you please suggest the bridge IC for converting the Class-D amplifier output to the line output ?
I am considering attenuating the output signal of the TPA3116D2 using the potentiometer, the operational amplifiers and outputting the attenuated signal to the line out output.
For the line driver DRV632 is reasonable, but the operational amplifiers that can attenuate the audio signal to approximately from -26 dB to 0 dB with the potentiometer are necessary.
So, could you please review the attached TINA-TI schematic which is designed based on the following application note ?
