1. Adopt TPA3118 digital power amplifier chip, small size design, BTL output Z high output power 50w, can drive 2 ohm speakers, can be balanced (differential) input, designed with mute control interface.
2. M is the mute control terminal, high-level mute (voltage 3.3v-12v), low-level operation, the default is working state, note: when mute control is needed, the resistance at the position needs to be removed, and external control is fine Up.
3. The signal input can be as follows: 1. Signal balanced input (differential): signal +, signal -, GND (ground); 2. Unbalanced input (single-ended):-terminal and GND (ground) Short-circuit, the signal is input from the + terminal. Product name: TPA3118 digital power amplifier board
