The "differential speaker output" is really a bridged speaker output that drives both speaker wires so that the voltage swing is doubled then the current is also doubled resulting in almost 4 times the power of a single-ended amplifier …

This topology is a two-pole (i.e. 12dB/octave) differential-in / single-ended out active low-pass filter. C1, C2, C3 and C4 plus R1, R2, R3, R4 and R6 determine the -3dB frequency. C5 AC couples R6, because the outputs of the CS4272 are DC biased at about 1/2 Vcc. These outputs can't drive significant DC current - thus a big coupling cap in C5.

The vintage way of getting differential audio signals from a single-ended input consisted of merely using an audio frequency transformer, usually a 2 pin input 3 pin output little thing, with a 1:1 turns ratio. The single-ended signal feeds the transformer input, and the output side is a differential signal pair you can bias to wherever you need it to be - connect the middle pin of …

The difference between the voltages at the plus and minus outputs is the output differential voltage, Vod. The output common-mode voltage, Voc, is the average of the two output voltages, and is controlled by the voltage at Vocm. With a(f) as the frequency-dependant differential gain of the amplifier, then Vod = Vid × a(f). Input voltage definition
