TEXAS INSTRUMENTS LM4990MM/NOPB 音频功率放大器, AB, 1通道, 2 W, 2.2V 至 5.5V, VSSOP, 8 引脚
The is an Audio Power Amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.25W of continuous average power to an 8R BTL load and 2W of continuous average power NGZ and DGQ only to a 4R BTL load with less than 1% distortion THD+N+N from a 5VDC power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. The LM4990 does not require output coupling capacitors or bootstrap capacitors and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. The LM4990 features a low-power consumption shutdown mode. To facilitate this, shutdown may be enabled by either logic high or low depending on mode selection.
