3 Description
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, cycleby-
cycle current limit, short circuit, clipping detection,
overtemperature warning and shutdown, and DC
speaker protection.
