B100 TDA7498E Digital Power Amplifier Dual BTL Class D Subwoofer Audio Amplifier w/ Power Adapter
Description:
-This power amplifier is a dual BTL class-D audio amplifier, specially provided for users who need to connect a high-power subwoofer, which can greatly increase the low-frequency effect. Digital power amplifier is a kind of amplifier with low distortion, low noise and large dynamic range. It is excellent in sound quality, transparency, resolution, and low frequency shock. The greater feature is its low power consumption, low heat generation and small size.
-High-performance analog class-D audio amplifier TDA7498E features excellent sound quality and driving force. The chip also has built-in noise suppression, standby function and mute function, most suitable for suppressing TDMA (time division multiple access) noise balanced input. With built-in intelligent current protection function, it can identify the frequency range of the peak current required by the speaker and automatically prevent the audio stream output from being interrupted.
Features:
-160W+160W output power at THD=10% with R, =4ohm and Vcc=36V
-Wide range single supply operation (14-36V)
-High efficiency: (85%)
-Parallel BTL function by MODE pin
-Four selectable, fixed gain settings of nominally 23.6dB, 29.6dB, 33.1dB and 35.6dB
-Differential inputs minimize commen-mode noise
-Standby and mute features
-Smart protection
-Thermal overload protection
-Small offset less than 20mV
-Power amplifier size: width 90mm, height 35mm, length, 108mm
Power Selection:
The power supply is a DC power supply, which can be a laptop power supply or a 16-30V DC power supply in a car. The outer diameter of the power interface is 5.5mm, and the inner insert is 2.1mm. In addition, the higher the voltage, the greater the output power, and the current is the same. The output power of a 6A power supply is larger than a 2A power supply.
Package List:
1 x Power Amplifier
1 x 24V 6A Power Adapter
Note:
-This power amplifier can be changed to full-frequency amplifier.
-Output power is 180Wx1, under DC 36V 3ohm test. The output power is related to the input power voltage and current and the impedance of the speaker. If you only input 16V power, the output power will not exceed 40W.
