Overview
The LA6516 is a two-output power amplifier developed
for use in both consumer and industrial equipment.
Functions
• High slew rate (1.0 V/µs)
• High output current (IOmax = 1.0 A)
• Current limiter function
• Wide operating voltage range (±2 to 18 V)
• Supports single-voltage power supply operation (4 to 36 V)
• Thermal shutdown function
• Muting circuit (Functions for both channels; when the
mute input is high the output will be on.)
