LM4906LDBD
具有内部可选增益的 1W、旁路电容器更少音频功率放大器
LM4906LDBD
概述
The LM4906 is capable of delivering 1W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a +5V power supply in a small LLP package.
It is the first National Semiconductor Boomer Power Amplifier that does not require an external PSRR bypass capacitor. In addition, no output coupling capacitors or bootstrap capacitors are required which makes the LM4906 ideally suited for cell phone and other low voltage portable applications.
This LM4906LDBD is an evaluation board designed to ease the evaluation and effort during the development of a circuit using the LM4906LD. It is an easy to use stand-alone board that requires power and GND, an input signal and an output load.
特性
- Selectable gain of 6dB (2V/V) or 12dB (4V/V)
- No output or PSRR bypass capacitors required
- Improved "Click and Pop" suppression circuitry
- Very fast turn on time: 5ms (typ)
- Minimum external components
- 2.6 - 5.5V operation
- BTL output can drive capacitive loads
- Ultra low current shutdown mode (SD Low)
- LLP footprint is 18% smaller than the MSOP footprint
Applications:
- Portable computers
- Desktop computers
- Multimedia monitors
