Frequently Asked Questions
What does 'output capacitor-less' mean for the LM4846TL?
Output capacitor-less means the LM4846TL does not require large electrolytic output coupling capacitors, which reduces the overall bill of materials cost and frees up significant PCB space. This feature is especially valuable in ultra-thin mobile devices where component height and footprint are tightly constrained.
How many channels does the LM4846TL support?
The LM4846TL integrates 3 audio amplifier channels, allowing designers to drive a stereo headphone output plus one additional mono channel such as a speaker or subwoofer from a single IC. This makes it ideal for portable multimedia devices requiring multiple simultaneous audio outputs.
What package is the LM4846TL available in?
The LM4846TL comes in a 25-ball BGA package with a 5x5 mm body and 20-pin equivalent code, offering an extremely small footprint suitable for high-density PCB layouts in thin portable consumer electronics and wearable audio devices.
What is the output power of the LM4846TL?
The LM4846TL delivers a nominal output power of 0.5W per channel, which is well-matched for headphone and small speaker driving in battery-powered devices where power efficiency and audio quality must be balanced to maximize playback time.
What are typical use cases for the LM4846TL?
Typical applications include smartphones, portable media players, handheld gaming consoles, and tablet PCs that need integrated multi-channel audio amplification. Its low power consumption, wide 20 kHz bandwidth, and compact BGA packaging make it a strong candidate for any mobile audio subsystem design.
