Mode selection
The three operating modes of the TDA7498 are set by the two inputs, STBY (pin 20) and
MUTE (pin 21).
The protection functions of the TDA7498 are realized by pulling down the voltages of the
STBY and MUTE inputs shown in
must be limited to 200 µA.

Standby mode: all circuits are turned off, very low current consumption.
Mute mode: inputs are connected to ground and the positive and negative PWM
outputs are at 50% duty cycle.
Play mode: the amplifiers are active.
