Frequently Asked Questions
How does LM4663MT/NOPB's Class D topology improve battery life in portable speaker applications compared to Class AB?
Class D amplifiers like LM4663MT/NOPB achieve efficiencies above 85%, compared to roughly 50-65% for Class AB designs, which means significantly less heat and longer battery run time when delivering 2.1 W per channel to speaker loads.
What audio performance does LM4663MT/NOPB deliver in terms of bandwidth and distortion figures?
LM4663MT/NOPB provides a 22 kHz bandwidth that covers the full human audible range (20 Hz to 20 kHz) and achieves 1% total harmonic distortion (THD), making it suitable for voice, music playback, and notification tones in consumer electronics.
What PCB footprint does the 24-pin TSSOP package of LM4663MT/NOPB require compared to a DIP alternative?
The 24-pin TSSOP package has a body width of approximately 4.4 mm and a 0.65 mm pin pitch, occupying roughly 70% less PCB area than an equivalent 24-pin DIP package, which is critical for slim tablet or smartphone audio board layouts.
Is LM4663MT/NOPB compliant with RoHS and REACH requirements for products sold in European markets?
Yes. LM4663MT/NOPB carries Pb-free (NOPB suffix), an e3 JEDEC finish code, and REACH compliance status, meeting all material restrictions for CE-marked audio products sold in the EU and other regulated markets.
