DC load detection is only available in I
The default setting is logic 0 for bit IB2[D2] which disables DC load detection. DC load
detection is enabled when bit IB2[D2] = 1. Load detection takes place before the class-D
amplifier output stage starts switching in Mute mode and the start-up time from Standby
mode to Mute mode is increased by t
The capacitor connected to pin SEL_MUTE (see
inaudible current test pulse, drawn from the positive amplifier output. The diagnostic
‘speaker load’ (or ‘open load’), based on the voltage difference between pins OUTxP and
OUTxN is shown in
