Low-leakage tantalum or ceramic capacitors are recommended. When polarized capacitors are used, the
positive side of the capacitor should face the amplifier input in most applications as the dc level there is held at
VCC/2, which is likely higher than the source dc level. Note that it is important to confirm the capacitor polarity in
each specific application. Recommended capacitor values are between 0.1
F and 1 F.

Figure 34 shows a Class-AB audio power amplifier (APA) in a bridge-tied-load (BTL) configuration. The
TPA6040A4 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).
