TDA7498E Digital Power Amplifier Board 2X160W Stereo BTL220W Mono High Power Digital Power Amplifier

High-power Class D digital amplifier

Amplifier chip: original TDA7498E (TDA7498L is a 2X80W chip, TDA7498 is a 2X100W chip, and TDA7498E is a 2X160W chip)

Output power: 2X160W (using a 4-ohm impedance speaker unit, input voltage 36V DC output power 160W+160W)

Working voltage: 15~36VDC with input polarity reverse protection (the real power of the speaker is large enough, the recommended voltage is 32V, 8A or more DC, the power supply power is too small, distortion and sound interruption will not produce a shocking effect.)

Speaker impedance: 4 ohms 6 ohms 8 ohms

Heat dissipation method: temperature-controlled forced air cooling (when the heat sink temperature reaches a certain level, the fan runs to force heat dissipation)

Work efficiency: 85% (official data)

Support BTL mode (back of the amplifier board J1, J2, J3, J4 short circuit) 36V power supply 3 ohm mono 220W output (TDA7498, TDA7498L chips do not support this function)
