Hi is there any classD chinese chipamp board featuring (differential) balanced input (preferably simply implemented as featured in the chip differential inputs) ?
I mean many monolithic amp ICs have differential inputs but often boards using them omit the differential input scheme ?
In fact I just want differential input but without adding opamp summung or additional stages ....
thanks

The cheapest ones I know of are these mono amps:
TPA3116 Mono Channel Digital Power Audio Amplifier Board BTL Out 100W DC 12V-24V | eBay
If you are looking for something with more power:
TDA8950-2x170W-Digital-Subwoofer-Class-D-Audio-Amplifier-Board - AliExpress
or even more power:
TDA8954-2x210W-Class-D-Amplifier-Board - eBay
This TDA7498E board also provides access to differential inputs but you have to remove R20 and R21:
TDA7498E-160W-160W-High-Power-digital-stereo-amplifier-board - AliExpress
On many other boards, you can get to the differential inputs to the chip by locating the bypass capacitors and removing some resistors.
