The TDA7498E amplifier offers flexible audio-system configuration, in both stereo and mono modes, and also includes the mono parallel feature for driving the subwoofer/woofer channel in 2.1 sound set-ups. To maximize the speaker output power, sound-system manufacturers require high-efficiency amplifiers capable of driving speakers at low impedances of 2 or 3 ohms, which creates a challenge by increasing device sizes. The device’s high-current capability not only delivers high output power, but also enables the design of platform solutions where the speaker impedance can be simply changed - from 8 down to 2 ohms - without any power or current limitation.
