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.
