Filterless, 2.65W, Mono, Class D Audio Power Amplifier
LM4673 Product Folder The LM4673 is a filterless 2.65W class D fully differential audio amplifier in a tiny 0.4mm pitch micro SMD package. The LM4673 is designed to meet the demands of mobile phones and other portable communication devices. It is capable of delivering 1.24 Watts of average power to an 8 ohm load with less than 1% distortion (THD+N) from a 5V DC power supply.
The LM4673SDBD is an evaluation board designed to ease evaluation and effort during the development of a circuit using the LM4673SD. The evaluation board includes a measurement filter. It is an easy-to-use stand-alone board that requires power and GND, a differential input signal and anoutput load.
Features:
- 9-bump 0.4mm pitch micro SMD package
- Very low iddq (2.6mA at 5V, 2.1mA at 3.6V)
- PSRR 78dB at 217Hz
- CMRR 70dB at 217Hz
- SNR 97dB
- THD+N 0.02% at 3.6V (Pout = 100mA)
Applications:
- Mobile phones
- PDAs
- Portable electronic devices and accessories
