Product Overview
The LM4991MA/NOPB 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. To conserve power in portable applications, the LM4991's micropower shutdown mode (ISD=0.1µA, typical) is activated when VDD is applied to the shutdown pin. Boomer audio power amplifier is designed specifically to provide high power, high fidelity audio output. It requires few external components and operates on low supply voltages from 2.2 to 5.5V. Since the LM4991 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is ideally suited for low-power portable systems that require minimum volume and weight. Additional LM4991 features include thermal shutdown protection, unity-gain stability and external gain set. No output coupling capacitors, snubber networks or bootstrap capacitors or gain-setting resistors required.
- Ultralow current shutdown mode
- Improved click and pop circuitry eliminates noise during turn-on and turn-off transitions
- Unity-gain stable
- 0.1µA (typical) Shutdown current
- 64dB PSRR
- Green product and no Sb/Br
