Can TPA301 be replaced with TPA3110?

problems with the power supply; 2. The power output is smaller; 3. The rectification performance is reduced; Solution: 1. Try to change the rectifier bridge; 2. Check whether the capacitor is caused by excessive current leakage; 3. Focus on checking the high-voltage board and power supply board, and use the switching power supply to supply the high-voltage board separately to see if it is normal, as normal.

TPA3110D2 has no accompanying sound, and the reasons are as follows: 1. Power supply problems; 2. The power output is smaller; 3. The rectification performance is reduced; Solution: 1. Try to change the rectifier bridge; 2. Check whether the capacitor is caused by excessive current leakage; 3. Focus on checking the high-voltage board and power supply board, and use the switching power supply to supply the high-voltage board separately to see if it is normal, as normal.

"Strange Tales from Liaozhai" has developed the short stories of ancient Chinese literary language to a new height, and since then, literary language has been difficult to be majestic. After "Strange Tales from Liaozhai", although there are Ji Yun's "Notes on Reading Wei Caotang", etc., it is difficult to become a climate. As soon as "Strange Tales from Liaozhai" came out, it became popular all over the world, and the reprinted editions appeared one after another, and the annotated editions and commentaries appeared one after another, becoming the bestsellers in the world.

Wenyan ** has also appeared again in the situation of prosperity. At this time, a large number of literary ** collections, Shen Qifeng's "Harmonic Duo", He Bang's "Ye Tan Sui Lu", Hao Gezi's "Firefly Window and Different Grass" and so on are mainly legendary notes**, most of the works are imitations of "Strange Tales from Liaozhai". Both the ideological content and the artistic level are inferior to "Strange Tales from Liaozhai". 7]

TPA3130 Pin Function:

Multiple output configurations are available in 21V with 2 50W (TPA3116D2) at 24V at 4 BTL, 2 30W (TPA3118D2) at 15V at 8 BTL, and 2 15W (TPA3130D2) at 8 BTL.

Wide voltage range: up to 26V.

High-efficiency Class D operation >90% power efficiency combined with low idle losses significantly reduces heat sink size Advanced modulation schemes.

The multiple switching frequency am suppresses the master-slave synchronization up to the switching frequency of .

Reduced PSU requirements due to the use of a feedback power clean-grade architecture with a high-rent positive posture PSRR.

Differential and single-ended inputs:

Stereo. Mode and Mono Mode (with a single filter mono configuration).

Single-supply operation reduces the number of components.

Integrated self-protection circuitry with protection against overvoltage, undervoltage, overtemperature, DC detection, and short circuit, as well as error reporting.

Thermally Enhanced Package DAD (32-pin HTSSOP package, pad.

Up-facing) DAP (32-pin HTSSOP package with pad down). Cons.

TPA3118 and 3116 are interchangeable and universal. TPA3116 belongs to digital power amplifier, and the effect depends on the circuit structure, production quality and process, and the power is also larger.

4 2 50W (TPA3116D2-Q1) at 24V under load and 2 30W at 8 BTL load (TPA3118D2-Q1) Wide voltage range: up to 26V High efficiency Class D operation It combines 90% power efficiency with low idle loss.

The power amplifier module is mainly divided into two parts: the switching power supply and the digital power amplifier, and the main function of the switching power supply part is to convert the alternating current.

The direct current required for the power amplifier is changed.

And provide sufficient current, the power amplifier part mainly completes the amplification of the audio signal, and provides the protection function of the power amplifier's own load.

TPA3116 power amplifier, 50Wx2 is 4 ohm output power, connected to 8 ohm speaker, it is only 25Wx2Change to 2 4ohm 40W woofers, and the output power will be half as large as a mountain. If you like high power, buy a 200wx24-8 ohm power amplifier board, and connect a 4 ohm speaker to 200wx2

8 ohms is 100wx2The online power amplifier board is 4-8 ohm output power, which looks big. In fact, the slag sail is the output power of 4 ohm sedan chair.
