产品概述
TEXAS INSTRUMENTS LM3886T 音频功率放大器， B， 1通道， 68 W， 20V 至 84V， TO-220， 11 引脚
The LM3886T 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 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.
