capacitors and differential LC filter as shown in Figure 20.

•

Pins 29, 30, 31, 36, 37, 38 - Power supply pins to half-bridges A, B, C, and D. A and B form a full-bridge and

C and D form another full-bridge. A 470-µF bulk capacitor is recommended for each full-bridge power pins.

Two 0.22-µF decoupling capacitors are placed on each full-bridge power pins. See Figure 20 for details.

10.2.2 Typical SE Configuration

See Figure 19 for application schematic. In this application, four single-ended PWM inputs are used with AD

modulation from the PWM modulator such as the TAS5558. AD modulation scheme is defined as PWM(+) is

opposite polarity from PWM(–). The single-ended (SE) output configuration is often used to drive four

independent channels in one TAS5622A device.
