5128 Power Amplifier Class D Digital Power Amplifier 5W Mono Audio Power Amplifier Module Low Distortion Single Power Supply -70000
product detail
Product Features
The 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.
