Compatibility with TDA7491 stereo BTL family
TDA7491MV mono BTL analog class-D amplifier is derived from the TDA7491 stereo
analog class-D BTL family. TDA7491MV has only the left channel of the stereo BTL family.
In order to guarantee the pin to pin compatibility when moving the application from stereo to
mono, it is necessary to connect the right channel inputs (pins 32 and 33 of TDA7491 BTL
family) to VCC and GND, that is, pin 32 to VDDS and pin 33 to SGND.
