TPA3220 is a pad-down Class-D amplifier that enables efficient operation at full-power, idle and standby. The device features closed-loop feedback with a bandwidth up to 100 kHz, which provides low distortion across the audio band and delivers excellent sound quality. The device operates with either AD or low idle-current HEAD (High Efficiency AD) modulation and can drive up to 2 x 60 W continuously or 2 x 110 W peak into 4-Ω load with the thermal pad on bottom connected to the PCB.

The TPA3220 features a single-ended or differential analog-input interface that supports up to 2 VRMS with four selectable gains: 18 dB, 24 dB, 30 dB and 34 dB. The TPA3220 also achieves >90% efficiency, low idle power (<0.25 W) and ultra-low standby power (<0.1 W). This is made possible through the use of 70-mΩ MOSFETs, an optimized gate drive scheme and low-power operating modes. TPA3220 includes a built-in LDO for easy integration in single-power-supply systems. To further simplify the design, the device integrates essential protection features including undervoltage, cycle-by-cycle current limit, short circuit, clipping detection, overtemperature warning and shutdown, as well as DC speaker protection.
