Semiconductors\Audio ICs\Audio AmplifiersTPA3221 100W Stereo/200W Mono Class-D AmplifiersTexas Instruments TPA3221 100W Stereo/200W Mono HD Analog-Input Class-D Amplifiers have three operating modes, standby, idle and full-power, which enables efficient operation. Providing low distortion across the audio band, the closed-loop feedback has a bandwidth up to 100kHz, delivering excellent sound quality. Other high-efficiency features are an output power of up to 2 x 105W into 4Ω load or 1 x 208W into 2Ω load and operating within either AD or low idle-current HEAD (High Efficient AD mode) modulation.
