13.3 Estimating the output power
When using the power amplifier in a mono BTL application, the inputs of the two channels
must be connected in parallel and the phase of one of the inputs must be inverted; see
Figure
single-ended demodulation filters.
To ensure a pop noise-free start-up, an RC time-constant must be applied to pin MODE.
The bias-current setting of the VI converter input is directly related to the voltage on pin
MODE. In turn the bias-current setting of the VI converters is directly related to the DC
output offset voltage. A slow dV/dt on pin MODE results in a slow dV/dt for the DC output
offset voltage, ensuring a pop noise-free transition between Mute and Operating modes. A
time-constant of 500 ms is sufficient to guarantee pop noise-free start-up; see
