TPA31xD2 Class-D Stereo Amplifiers

Texas Instruments TPA31xD2 Class-D Stereo Amplifiers are stereo-efficient, digital amplifier power stage devices for driving speakers up to 100W/2Ω in mono. The high-efficiency characteristics allow these amps to do 2 x 15W without an external heat sink on a single layer PCB. The TPA3118D2 can run 2 x 30W/8Ω without a heat sink on a dual-layer PCB. If higher power is needed, the TPA3116D2 does 2x50W/4Ω with a small heat sink attached to its top-side power pad. All three devices share the same footprint, enabling a single PCB to be used across different power levels. TI TPA31xD2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences. This is achieved together with a master/slave option, making it possible to synchronize multiple devices.
