TPA3255 High Performance Class D Power Amplifier Board 2.0 Channel Mini Digital Audio Stereo Amplifier Module

TPA3255 High Performance Class D Power Amplifier Board 2.0 Channel Mini Digital Audio Stereo Amplifier Module

Description:
- TPA3255 is a high-performance class D amplifier with class D efficiency that can deliver truly high-end sound quality. This device features advanced integrated feedback design and proprietary high-speed gate holding ultra-low distortion, while exhibiting perfect sound quality. The device is operating in AD mode. When THD is 10%, it can drive up to 2 x 315W/4R loads and 2 x 150W 2VRMS analog input interfaces. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power idle loss (less than 2, this solution can significantly reduce idle loss).

Features:
- Using original TPA3255.
- The computing end adopts replaceable DIP-8 operational amplifiers x 2, and buyers can upgrade the computing model themselves.
- 2 x high-performance audio operational amplifier NE5532P for TI
- Main filter electrolytic capacitor 2200UF/63V x 2, 6 x FW series 10UF gold audio input coupling capacitors for Nichicon. Other filtering capacitors are imported high-quality capacitors.
- The audio digital class D amplifier uses 7W 14A inductors to ensure clear and powerful sound.
