Tpa318d2dapr htssop-32 audio power amplifier has the lowest price
explain
Tpa31xxd2 series is an efficient stereo digital amplifier power stage, which is used to drive speakers up to 100W / 2 Ω in mono mode. The efficiency of tpa3130d2 is very high. It can provide 2 on a single-layer PCB × 15W of external power is not required. Tpa3118d2 can even provide 2 on a double-layer PCB without using an external radiator × 30W / 8 Ω power.
If you need higher power, you can choose tpa3116d2. This device can provide 2 power supplies after connecting a small radiator to its top powerpad × 50W / 4 Ω power. The three devices are of the same size, so that a single PCB can meet the needs of different power levels. Tpa31xxd2 advanced oscillator / PLL circuit adopts a multi switching frequency option to suppress am interference; When the master-slave option is selected, multiple devices can also be synchronized.
Tpa31xxd2 device has short-circuit protection, thermal protection, overvoltage, undervoltage and DC protection, which can comprehensively prevent faults. In case of overload, the device will feed back the fault condition to the processor to avoid damage to itself.
