Figure 35 shows a Class-AB audio power amplifier (APA) in a bridge-tied-load (BTL) configuration. The
TPA6047A4 speaker amplifier consists of two Class-AB differential amplifiers per channel driving the positive and
negative terminals of the load. Specifically, differential drive means that as one side of the amplifier (the positive
terminal, for example) is slewing up, the other side is slewing down, and vice versa. This doubles the voltage
swing across the load as opposed to a ground-referenced load, or a single-ended load. Power is proportional to
the square of the voltage. Plugging 2x VO(PP) into the power equation yields 4X the output power from the same
supply rail and load impedance as would have been obtained with a ground-referenced load (see Equation 3).
