Advanced EMI SuppressionTechnology enables the use of inexpensive ferritebead filters at the outputs while meeting EMCrequirements. SpeakerGuardв„ў speaker protectioncircuitry includes an adjustable power limiter and aDC detection circuit. The adjustable power limiterallows the user to set a «virtual» voltage rail lowerthan the chip supply to limit the amount of currentthrough the speaker. The DC detect circuit measuresthe frequency and amplitude of the PWM signal andshuts off the output stage if the input capacitors aredamaged or shorts exist on the inputs. 1 15-W/ch into an 8-Ω Loads at 10% THD+N Froma 16-V Supply10-W/ch into 8-Ω Loads at 10% THD+N From a …

The high efficiency of theTPA3130D2 allows it to do 2 Г— 15 W without externalheat sink on a single layer PCB. The TPA3118D2 caneven run 2 Г— 30 W / 8 Ω without heat sink on a duallayer PCB. If even higher power is needed theTPA3116D2 does 2 Г— 50 W / 4 Ω with a small heatsink attached to its top side PowerPAD. All threedevices share the same footprint enabling a singlePCB to be used across different power levels. 1 Supports Multiple Output Configurations– 2 Г— 50 W Into a 4-О BTL Load at 21 V(TPA3116D2)– 2 Г— 30 W Into a 8-О BTL Load at 24 V(TPA3118D2)– 2 Г— 15 W Into a 8-О BTL Load at 15 V …
