FEATURES
DESCRIPTION
?Active Enabled Integrated Feedback Provides:
(PurePath?HD)The TAS5615is a high-performance analog input
CLass D amplifier with integrated closed loop –Signal Bandwidth up to80kHz for High
feedback technology(known as PurePath?HD).It Frequency Content From High Definition
has the ability to drive up to160W(1)Stereo into8?Sources
speakers from a single50V supply.
–Ultra Low0.03%THD at1W into8?
PurePath?HD technology enables traditional –0.03%THD Across all Frequencies for
AB-Amplifier performance(<0.03%THD)levels while Natural Sound at1W
providing the power efficiency of traditional class D –80dB PSRR(BTL,No Input Signal)amplifiers.
–>100dB(A weighted)SNR
Ultra Low0.03%THD+N is flat across all frequencies,–Click and Pop Free Startup ensuring that the amplifier doesn’t add uneven
distortion characteristics,and helps maintain a natural –Minimal External Components Compared to
sound.

This integrated circuit can be damaged by ESD.Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure.Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DEVICE INFORMATION
Terminal Assignment
The TAS5615is available in two thermally enhanced packages:?64-Pin QFP (PHD)Power Package ?44-Pin PSOP3package (DKD)
The package type contains a heat slugs that is located on the top side of the device for convenient thermal coupling to the heat sink.

APPLICATION INFORMATION
PCB MATERIAL RECOMMENDATION
FR-4Glass Epoxy material with2oz.(70μm)is recommended for use with the TAS5615.The use of this material can provide for higher power output,improved thermal performance,and better EMI margin(due to lower PCB trace inductance.
PVDD CAPACITOR RECOMMENDATION
The large capacitors used in conjunction with each full-bridge,are referred to as the PVDD Capacitors.These capacitors should be selected for proper voltage margin and adequate capacitance to support the power requirements.In practice,with a well designed system power supply,1000μF,63V will support more applications.The PVDD capacitors should be low ESR type because they are used in a circuit associated with high-speed switching.
DECOUPLING CAPACITOR RECOMMENDATIONS
In order to design an amplifier that has robust performance,passes regulatory requirements,and exhibits good audio performance,good quality decoupling capacitors should be used.In practice,X7R should be used in this application.
The voltage of the decoupling capacitors should be selected in accordance with good design practices. Temperature,ripple current,and voltage overshoot must be considered.This fact is particularly true in the selection of the2.2μF that is placed on the power supply to each half-bridge.It must withstand the voltage overshoot of the PWM switching,the heat generated by the amplifier during high power output,and the ripple current created by high power output.A minimum voltage rating of63V is required for use with a50.0V power supply.
SYSTEM DESIGN RECOMMENDATIONS
The following schematics and PCB layouts illustrate"best practices"in the use of the TAS5615.
