Vender Dual Channel Stereo High Power Digital Audio Power Amplifier Board TDA8954 Amplifiers 210W+210W Amplificador DIY al mejor precio

The TDA8954 digital power audio amplifier board has a wide operating voltage range of +/- 12.5V to +/- 42.5V. Not only supports AC power, but also DC power. The power amplifier adopts two es of dual-channel OCL or mono BTL bridge. Perfect protection: overvoltage protection, output current limit. High efficiency and low quiescent current. Fixed frequency: The clock switching frequency can be externally synchronized. The power switch has no "pop" sound and zero dead zone PWM output switch. High power output: as a single-ended amplifier, output 2x210W, Vp = +/- 40V, RL = 4; as a BTL amplifier, BD ulation, low noise, output 420W. Chip: TDA8954 Amplifier type: Class D Amplifier design: dual-channel stereo high-power amplifier Audio input: differential input or single-ended input Output power: 210W + 210W (mono BTL) 1 * 420W, RL = 8Ohm Frequency response: 20 hz-20khz Output impedance: 4 ohm-8ohm Working voltage: dual AC16V-dual AC28V (dual AC24V recommended voltage) Cooling device: aluminum radiator instruction: 1. The power amplifier board can be used as a pure PA, only connected to the power, or it can be connected to a preamplifier or tuning device. 2. The power amplifier board is equipped with +12V DC voltage output port, which is convenient for connection with external equipment.
