5W Mono Power Amplifier Module
The 5w mono power amplifier module adopts AB/D class LTK5128 power amplifier IC, low EMI and low quiescent current, no external low-pass filter is required, and the efficiency is up to 90% in the class D power amplifier mode mode. The DRC (Dynamic range) unique inside the LTK5128 Control) Correction circuit technology reduces the distortion caused by waveform chopping when the high power output is reduced. Compared with similar products, the dynamic response is better. With short circuit current protection, under voltage protection, overheat protection.
The power supply voltage is 2.5-5.5V, more than 5.5V, the chip will burn out
The supply current is recommended to be 1A or more. Below 1A, the sound will be small.
The positive and negative poles of the power supply cannot be reversed, and the reverse chip is burned.
Load recommended 4 Euro 3W speakers
This module has a mute switch, high level mute, low level playback, default is low level playback
This module is suitable for amplifying the audio signal of 0.5V-1V. If the signal is too small, it needs to be connected to the preamplifier.
This module is only suitable for single-supply operation and cannot be connected to a negative power supply.
