LM3886 具有静音功能的高性能 68W 音频功率放大器

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4 load and 38W into 8 with 0.1% THD+N from 20Hz-20kHz.

The performance of the LM3886, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe™) protection circuitry, puts it in a class above discrete and hybrid amplifiers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are completely safeguarded at the output against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks.

The LM3886 maintains an excellent signal-to-noise ratio of greater than 92dB with a typical low noise floor of 2.

LM3886 特性

68W cont. avg. output power into 4 at VCC = ±28V
38W cont. avg. output power into 8 at VCC = ±28V
50W cont. avg. output power into 8 at VCC = ±35V
135W instantaneous peak output power capability
Signal-to-Noise Ratio >= 92dB
An input mute function
Output protection from a short to ground or to the supplies via internal current limiting circuitry
Output over-voltage protection against transients from inductive loads
Supply under-voltage protection, not allowing internal biasing to occur when |VEE| + |VCC| <= 12V, thus eliminating turn-on and turn-off transients
11-lead TO-220 package
Wide supply range 20V - 94V
