DESCRIPTION
The LM4666 is a fully integrated single-supply high efficiency switching audio amplifier. It features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces parts count,
simplifies circuit design, and reduces board area. The LM4666 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators.

FEATURES
• No Output Filter Required for Inductive Transducers
• Selectable Gain of 6dB or 12dB
• Very Fast Turn On Time: 6ms (typ)
• Minimum External Components
• "Click and Pop" Suppression Circuitry
• Micro-Power Shutdown Mode
• Short Circuit Protection
• Available in Space-Saving NHK0014A Package

APPLICATIONS
• Mobile Phones
• PDAs
• Portable Electronic Devices

KEY SPECIFICATIONS
• Efficiency at 3V, 100mW into 8Ω Transducer: 79% (typ)
• Efficiency at 3V, 450mW into 8Ω Transducer: 84% (typ)
• Efficiency at 5V, 1W into 8Ω Transducer: 85% (typ)
• Total Quiescent Power Supply Current: 7.0mA (typ)
• Total Shutdown Power Supply Current: 0.02µA (typ)
• Single supply range: 2.8V to 5.5V
