Power limiter function
An adjustable power limiting function has been integrated to protect "small speakers"
applications: thanks to this feature, it's possible to limit by configuration the max power
delivered to the load.
Taking advantage of digital input architecture, the output power limitation is obtained through
the management of the input signal. It's important to underline that the limitation is
implemented independently of the supply voltage value.
The intervention thresholds, configurable through I2C are listed in the table below
The limitation is gradual in order to have no impact on the acoustic performance. Depending
on the signal amplitude and the desired attenuation, different gains are applied to the signal
itself.
Here an example of the response obtained with a limitation corresponding to 80% of the full-
scale: the blue line represents the signal when the power limiter is not employed, while the
red line is the result of the applied attenuation.

1. 19 V is only a reference level, coherently with "standard gain" value in Section 5.3, to deduce the power
limiter thresholds. The reference level is unreachable due to the maximum supply voltage range, equal to
18 V.
