Texas Instruments TAS5611
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 Ω Speakers from a single 32.5V supply. DEVICE INFORMATION Terminal Assignment The TAS5611 is available in two thermally enhanced packages: • 64-Pin QFP (PHD) Power Package • 44-Pin PSOP3 package (DKD) The package types contain heat slugs that are located on the top side of the device for convenient thermal coupling to the heat sink.FEATURES
1●23 PurePath™ HD Enabled Integrated Feedback Provides:
APPLICATIONS
● Home Theater Systems● AV Receivers – Signal Bandwidth up to 80kHz for High Frequency Content From HD Sources
● DVD/Blu-ray Receivers
● Mini Combo System – Ultralow 0.03% THD at 1W into 4Ω
● Active Speakers and Subwoofers – Flat THD at all Frequencies for Natural Sound
DESCRIPTION
– 80dB PSRR (BTL, No Input Signal) – >100dB (A weighted) SNR – Click and Pop Free Startup● Pin compatible with TAS5630, TAS5615 and TAS5613
● Multiple Configurations Possible on the Same PCB With Stuffing Options: – Mono Parallel Bridge Tied Load (PBTL) PurePath™ HD technology enables traditional AB-Amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class D amplifiers. – Stereo Bridge Tied Load (BTL) – 2.1 Single Ended Stereo Pair and Bridge Tied Load Subwoofer
● Total Output Power at 10%THD+N – 250W in Mono PBTL Configuration into 2Ω Unlike traditional Class D amplifiers, the distortion curve only increases once the output levels move into clipping.
