- Eliminates SE amplifier output coupling capacitors
- Advanced "click and pop" suppression circuitry
- Stereo headphone amplifier mode
- Low-power standby and ultra-low current micropower shutdown modes
- Thermal shutdown protection circuitry n 2.4V to 5.5V operation
- Unity-gain stable
- Gain set with external resistors
Applications
- PDAs Notebook puters Cellular phones Handheld portable electronic devices
