Frequently Asked Questions
What is the output power and channel count of the LM48410SQ/NOPB?
The LM48410SQ/NOPB delivers 2.3W per channel in stereo (2-channel) configuration. It achieves this output with a fixed gain of 24 dB and maintains total harmonic distortion at just 1%, making it suitable for high-quality portable audio applications.
What does filterless mean for the LM48410SQ/NOPB and why does it matter?
Filterless operation means the LM48410SQ/NOPB uses a proprietary modulation scheme that eliminates the need for external LC output filters. This reduces PCB area, lowers BOM cost, and minimizes EMI radiation—critical advantages in compact consumer devices like tablets and portable speakers.
What package does the LM48410SQ/NOPB use and what are the key specs?
The LM48410SQ/NOPB is housed in a 24-pin Quad Flat No-Lead (QFN) package (JESD-30 code S-XQCC-N24). Key specs include 2.3W stereo output, 24 dB gain, 1% THD, 88 dB noise figure (SNR), and a 2-channel Class D topology with low EMI design.
What are typical applications for the LM48410SQ/NOPB?
The LM48410SQ/NOPB is designed for consumer electronics requiring compact, efficient audio amplification. Typical applications include smartphones, tablets, Bluetooth portable speakers, portable media players, laptop audio systems, and gaming devices where low EMI and small form factor are essential.
Is the LM48410SQ/NOPB RoHS compliant and what does the NOPB suffix mean?
Yes, the LM48410SQ/NOPB is fully RoHS compliant. The NOPB suffix stands for 'No Lead (Pb) Free,' confirming the device meets JESD-609 e3 standard for lead-free soldering. The Pb-free code is confirmed as Yes, making it suitable for environmentally conscious manufacturing.
