Description
TPA3221 is a high-power Class-D amplifier with 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 1SPW modulation, and can drive up to 2 x 100 W into 4-Ω load or 1 x 200 W into 2-Ω load.
