Product Description

The LM3886TF is an Overture high performance class AB audio power amplifier with mute function in 11 pin TO-220 package. The LM3886 utilizes self peak instantaneous temperature (°Ke) (SPiKe) protection circuitry. This leads to high performance above discrete and hybrid amplifiers by providing an inherently and dynamically protected safe operating area (SOA). SPiKe protection provides output protection against overvoltage, undervoltage, overloads, including shorts to 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 2µV. It provides excellent linearity with an IMD (SMPTE) typical rating of 0.004%.
68W continuous average output power into 4ohm load at VCC=±28V
38W continuous average output power into 8ohm load at VCC=±28V
50W continuous average output power into 8ohm load at VCC=±35V
135W instantaneous peak output power capability
Output protection from short to ground or to supplies via internal current limiting circuitry
Output over voltage protection against transients from inductive loads
Wide supply voltage range from 20V to 84V
19V/µs slew rate
Common mode rejection ratio is 110dB
Operating temperature range 0°C to 70°C
This device has limited built-in ESD protection. The leads should be shorted together or device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
