Preliminary speciﬁcation

Power ampliﬁer with load detection and

auto BTL/SE selection

TDA8586

Notes

1. Tolerances on the mute level is tight because of the usage of this pin for integration during load detection.

2. The output power is measured directly on the pins of the IC.

3. The noise output is measured in a bandwidth of 20 Hz to 20 kHz.
