The Texas Instruments TPA3223DDVR is an active Class-D audio amplifier featuring analog input and supporting stereo or mono configurations. It operates with a wide power stage supply voltage range from 10V to 45V.
This amplifier delivers up to 200W in stereo mode into a 4 Ohm load at 10% THD+N, and up to 425W in mono mode into a 2 Ohm load. It boasts a low THD+N of less than 0.02% at 1W into 4 Ohms, high PSRR of 60dB, and low output noise of less than 100 µV (A-weighted). Selectable gains of 20 dB, 23.5 dB, 32 dB, and 36 dB are available.
Designed for efficiency, it achieves up to 90% Class-D operation. The device includes integrated protection features such as undervoltage, overvoltage, overcurrent, short circuit, and overtemperature protection. It is housed in an HTSSOP package with dimensions of 14 mm x 8.1 mm.
Key features include multiple input options for simplified pre-amp design, low-power operating modes like mute and shutdown, and the ability to synchronize multiple devices. Its robust design makes it suitable for various audio applications requiring high power and performance.
The TPA3223DDVR delivers up to 200W per channel stereo into 4 Ω (10% THD+N), 300W mono into 3 Ω (10% THD+N), and 425W mono into 2 Ω (10% THD+N).
The TPA3223DDVR has a typical efficiency of 90% into 4 Ω.
The TPA3223DDVR has a maximum THD+N of 0.02% at 1W into 4 Ω.
The TPA3223DDVR operates from -40°C to 85°C.
The TPA3223DDVR is available in a 44-pin HTSSOP (DDV) package measuring 14 mm x 8.1 mm.
The power stage supply voltage range is 10V to 45V.
The TPA3223DDVR offers selectable gains of 20 dB, 23.5 dB, 32 dB, and 36 dB.
