The TPA3116D2DADR series are high-efficiency stereo digital amplifier power stages for driving speakers up to 100W/2Ω in mono mode. The TPA3116D2DADR is very efficient, delivering 2 × 15W on a single-layer PCB without the need for an external heat sink. The TPA3116D2DADR can even deliver 2 × 30W/8Ω on a double-layer PCB without using an external heat sink. If higher power is required, the TPA3116D2 can be selected, which provides 2 × 50W/4Ω with a small heatsink connected to its top PowerPAD. All three devices are the same size so that different power levels can be met using a single PCB.

The TPA3116D2DADR advanced oscillator/PLL circuit employs a multiple switching frequency option to suppress AM interference; with optional master-slave options, it also allows multiple devices to be synchronized.

The TPA3116D2DADR device is fully protected against failures with short-circuit and thermal protection, as well as overvoltage, undervoltage, and DC protection. During overload conditions, the device protects itself from damage by feeding the fault condition back to the processor.
