The maximum output power is 220W for a single channel at 8 Ohms and 125W for two channels at 4 Ohms.
- What is the supply voltage range for this amplifier?
The supply voltage range is from ±12.5 V to ±32.5 V.
- What type of protection does the TDA8920TH/N1,118 offer?
The device offers overvoltage, overtemperature, and overcurrent protection.
- Can the TDA8920TH/N1,118 be used in both mono and stereo configurations?
- What is the operating temperature range of the TDA8920TH/N1,118?
The operating temperature range is from -40°C to 85°C.
- What package type is the TDA8920TH/N1,118 available in?
The device is available in a 24-HSOP (Heat Sink On Package) surface mount package.
- Does the TDA8920TH/N1,118 have mute and standby functions?
- How does the Thermal FoldBack (TFB) function work?
The TFB function gradually reduces the output power within a defined temperature range to stabilize the temperature and prevent overheating.
- What happens if the temperature continues to rise despite TFB?
If the temperature continues to rise, the OverTemperature Protection (OTP) is activated, shutting down the device until the temperature drops below the threshold.
- Is the TDA8920TH/N1,118 suitable for professional audio equipment?
