Stereo and Mono BTL Operation Selection using the MODE Pin
The TDA7498E can be used in stereo applications or mono BTL applications. Connecting the MODE pin to the VDDS pin configures the device in mono BTL. The output of the two channels can be paralleled. When the MODE pin is connected to ground or floating (pulled down internally) the device works as a stereo amplifier.
Gain Setting
The gain of the TDA7498E is set by GAIN (pin 30).
Smart Protection
To avoid dynamic impedance drop, two overcurrent thresholds are set. The first threshold is for the overcurrent limit. The device limits the output current to the first threshold but does not shut down the PWM outputs.
If the device is shorted and at least one of the two output currents reaches the second threshold, the device is shut down immediately. The device will recover automatically when the fault is removed from the BTL outputs.
