    Hello iehncent,

    The TPA2054D4 and TPA2050D4 are not quite pin to pin compatible.  The TPA2054D4 has an extra Mono differential input.  Also, the TPA2054D4 has a Class-D gain of +6 dB, whereas in the case of the TPA2050D4 it's 0 dB.

    Please see attached diagram showing pinout differences.
