The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.
The TPA3251 delivers a better performance with a lower THD+N (<0.005% @1W into 4Ω) and a signal bandwidth of up to 100kHz for true Ultra-HD / High Resolution sound while supporting output levels up to 175W Stereo / 350W Mono.
TPA3255 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. For applications with higher power requirements, the TPA3255 delivers the same performance as the TPA3251 for output levels up to 315W Stereo /600W Mono.
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
The TAS5615 is a high-performance analog input class-D amplifier with integrated closed-loop feedback technology (known as PurePath HD technology). It has the ability to drive up to 160 W(1) stereo into 8- speakers from a single 50-V supply.
PurePath HD technology enables traditional AB-amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class-D amplifiers.
Ultralow 0.03% THD+N is flat across all frequencies, ensuring that the amplifier does not add uneven distortion characteristics, and helps maintain a natural sound.
The efficiency of this class-D amplifier is greater than 90%. Undervoltage protection, overtemperature, clipping, short-circuit and overcurrent protection are all integrated, safeguarding the device and speakers against fault conditions that could damage the system.
(1) Achievable output power levels are dependent on the thermal configuration of the target application. A high performance thermal interface material between the package exposed heatslug and the heat sink should be used to achieve high output power levels
