LM4991 Overview
Key Specifications
Package: SOIC
Mount Type: Surface Mount
Pins: 8
Max Voltage (typical range): 5.5 V
Description
The LM4991 is a mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 3Ω load with less than 10% THD when powered by a 5V power supply (Note 1). To conserve power in portable applications, the LM4991’s micropower shutdown mode (ISD = 0.1µA, typ) is activated when VDD is applied to the SHUTDOWN pin.
Key Features
- No output coupling capacitors, snubber networks, bootstrap capacitors or gain-setting resistors required
- Unity-gain stable n n n n
