T he T K2150 (T C2001/T P2150 chipset) is a two-channel, 200W (6Ω ) per channel Amplifier

Driver that uses T rip ath’s proprietary Digital Power Processing (DPP ^{T M}

)

technology.

Class-T amplifiers offer both the audio fidelit y of Class-AB and the power efficiency of

Class-D amplifiers.

Typical Performance for TK2150

THD+N versus Output Power versus Supply Voltage

R_L= 6Ω

Vs = +35V, +40V, +45V

f = 1kHz

BBM = 40nS

BW = 22hZ - 20kHz(AES17)

NOTE: +45V test uses R_FBC=11kΩ
