DESCRIPTION
Sound
– 80dB PSRR (BTL, No Input Signal) The TAS5611 is a high performance analog input
Class D amplifier with integrated closed loop
– >100dB (A weighted) SNR
feedback technology (known as PurePath™ HD) with
– Click and Pop Free Startup
the ability to drive up to 125W

PurePath™ HD technology enables traditional
• Multiple Configurations Possible on the Same
AB-Amplifier performance (<0.03% THD) levels while
PCB With Stuffing Options:
providing the power efficiency of traditional class D
amplifiers.
– Mono Parallel Bridge Tied Load (PBTL)
– Stereo Bridge Tied Load (BTL)
Unlike traditional Class D amplifiers, the distortion
curve only increases once the output levels move into

clipping. PurePath™ HD Power PAD™
Tied Load Subwoofer
PurePath™ HD technology enables lower idle losses
• Total Output Power at 10%THD+N
making the device even more efficient.
– 250W in Mono PBTL Configuration into 2Ω
– 125W per Channel in Stereo BTL
Configuration into 4Ω
• Total Output Power in BTL configuration at
1%THD+N
– 130W Stereo into 3Ω
– 105W Stereo into 4Ω
– 70W Stereo into 6Ω
– 55W Stereo into 8Ω
• >90% Efficient Power Stage With 60-mΩ
Output MOSFETs
• Self-Protection Design (Including
Undervoltage, Overtemperature, Clipping, and
Short-Circuit Protection) With Error Reporting
• EMI Compliant When Used With
Recommended System Design
• Two Thermally Enhanced Package Options:
(1) Achievable output power levels are dependent on the thermal
– PHD (64-Pin QFP)
configuration of the target application. A high performance
– DKD (44-Pin PSOP3)
thermal interface material between the package exposed
heatslug and the heat sink should be used to achieve high
output power levels.
