具有可选电容耦合或 OCL 输出的汽车类 40mW 立体声耳机放大器 10-VSSOP -40 to 105
The LM4911/LM4911Q is an stereo audio power amplifier capable of delivering 40mW per channel of continuous average power into a 16Ω load or 25mW per channel into a 32Ω load at 1% THD+N from a 3V power supply.
Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4911/LM4911Q does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. In addition, the LM4911/LM4911Q may be configured for either single-ended capacitively coupled outputs or for OCL outputs patent pending.
The LM4911/LM4911Q features a low-power consumption shutdown mode and a power mute mode that allows for faster turn on time with less than 1mV voltage change at outputs on release. Additionally, the LM4911/LM4911Q features an internal thermal shutdown protection mechanism.
The LM4911/LM4911Q is unity gain stable and may be configured with external gain-setting resistors.
A Q-grade version is available for automotive applications. It is AEC-Q100 grade 2 qualified and packaged in a 10–pin MSOP package LM4911QMM.
