Philips Semiconductors 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.
