TDA8954 Digital Amp Board 210W+210W Class D 2.0 Audio Power Amplifier Parameters: Chip: TDA8954TH Type: Class D Design: two-channel stereo Audio input: differential input or single-ended input Power output: 210W + 210W connect (mono BTL) 1 × 420W, RL = 8Ω Frequency response: 20Hz-20KHz Output impedance: 4Ω-8Ω Operating voltage: Dual AC16V-AC28V (Recommend 24V-0-24V) Filter capacitor: 1000UF * 10 = 10000UF storage Radiator: Aluminum Radiator Features: Amplifier board can be connected to two-channel OCL or mono BTL bridged modes, amplifier board ship default is two-channel OCL mode, mono BTL mode, you can set up their own. Amplifier board supports both AC and DC power supply. Amplifier board can use as a pure power amplifier, plug in the power, you can also add the preamp and tuning equipment. Operating voltage range: ± 12.5V- ± 42.5V (stereo fully differential input or single-ended input) It can be composed of single-ended amplifier or bridge amplifiers High power output: in Vp = ± 39V, RL = 3 ohms, as a single-ended amplifier output 2X234W, in Vp = ± 41V, RL = 4 ohms, you can output 2X210W, in Vp = ± 41V, RL = 8 ohm, as BTL amplifier output 420W.Muse Audio
