The LM4980 is a stereo headphone audio amplifier, whichwhen connected to a 3.0V supply, delivers 42mW to a 16?load with less than 1% THD+N. With the LM4980 packagedin the SD package, the customer benefits include low profileand small size. This package minimizes PCB area and maximizesoutput power.The LM4980 features circuitry that significantly reduces outputtransients (“clicks” and “pops”) while driving headphonesduring device turn-on and turn-off without costly externaladditional circuitry. The LM4980 also includes an externallycontrolled low-power consumption active-low shutdownmode, and thermal shutdown. Boomer audio power amplifiersare designed specifically to use few external componentsand provide high quality output power in a surfacemount package.
- 2-cell 1.5V to 3.3V battery operation
- Unity-gain stable
- “Click and pop” suppression circuitry for shutdown and power on/off transient with headphone loads
- Active low micro-power shutdown
- Thermal shutdown protection circuitry
