TPA3223 is a high-power Class-D amplifier that enables efficient operation at full-power, idle and standby. The device features closed-loop feedback which provides low distortion across the audio band and delivers excellent sound quality. The device operates in AD modulation and can drive up to 2 x 200 W into 4-Ω load or 1 x 400 W into 2-Ω load.

The TPA3223 features a single-ended or differential analog-input interface that supports up to 2 VRMS with four selectable gains: 20 dB, 23.5 dB, 32 dB and 36 dB. The TPA3223 also achieves >90% efficiency, low idle power and ultra-low standby power (<0.1 W). This is made possible through the use of 60-mΩ MOSFETs, an optimized gate drive scheme and low-power operating modes. To further simplify the design, the device integrates essential protection features including undervoltage, overvoltage, cycle-by-cycle current limit, short circuit, clipping detection, overtemperature warning and shutdown, and DC speaker protection.
