Description
TPA3221 is a high-power Class-D amplifier that enables efficient operation at full-power, idle and standby. The device features closed-loop feedback with a bandwidth up to 100kHz, 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 Efficient AD mode) modulation, and can drive up to 2 x 105W into 4andOmega; load or 1 x 208W into 2andOmega; load.
The TPA3221 features a single-ended or differential analog-input interface that supports up to 2VRMS with four selectable gains: 18dB, 24dB, 30dB and 34dB. The TPA3221 also achieves andgt;90% efficiency, low idle power (andlt;0.25W) and ultra-low standby power (andlt;0.1W). This is made possible through the use of 70mandOmega; MOSFETs, an optimized gate drive scheme and low-power operating modes. TPA3221 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.
