Part Number: TPA3128D2
Other Parts Discussed in Thread: TPA3250, TPA3116D2EVM

Hello TI engineer,

I am the engineer of buddhiaudio. I found that for3116 3118 3128 chips， if it works at freq higher than 400khz,the distortion will be lower.But there is a trade off in power consumption of chips.

I want more details in distortion performance of tpa3128 3118 or 3116 and suggest you do tests .  Actually the similar questions exists in tpa3250. which is also our considered chip type.
