DESCRIPTION

FEATURES

* Work stably within a wide power suppy voltage range(vcc=25 to 60V). * Contain a relay driver(Max I 6=80mA) * Work as either latching function or automatic resetting function by using pin 3. (in both overload detection and output offset detection, either function can be selected.) * Need only single power supply * Both positive and negative output offset can be detected through the same pin.(output offset detection through pin 2) * AC voltage can be detected.(for AC-power OFF mute through pin 4) * The time delay from amplifier power ON to relay ON can be freely set by selecting external components.(For AC-power-ON mute through pin 7) * The moment that amplifier-power is turned off, it can make relay broken OFF and then loudsperker disconnected from amplifier to prevent a shock off noise.
