The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.
Delivers a better performance with a lower THD+N (<0.005% @1W into 4Ω) and a signal bandwidth up to 100kHz for true Ultra-HD / High Resolution sound while supporting output levels up to 175W Stereo / 350W Mono.
TPA3245 – 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 lower power requirements, the TPA3245 delivers the same performance as the TPA3251 for output levels up to 115W Stereo / 230W Mono.
TAS5611A – The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device.
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
The TAS5611 is a high performance analog input Class D amplifier with integrated closed loop feedback technology (known as PurePath™ HD) with the ability to drive up to 125W.(1) Stereo into 4 to 8 Speakers from a single 32.5V supply.
PurePath™ HD technology enables traditional AB-Amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class D amplifiers.
Unlike traditional Class D amplifiers, the distortion curve only increases once the output levels move into clipping.
PurePath™ HD technology enables lower idle losses making the device even more efficient.
(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
