Mike Polacek Quotations

National's Class D audio amplifier portfolio continues to meet our customers' design requirements for great audio performance in small, low- power, low-heat portable applications. Our new LM4673 mono Class D amplifier comes in a tiny, 0.4 mm-pitch micro SMD package to save space in manufacturers' designs. The stereo LM4674 Class D amplifier also provides great board-space efficiency for stereo applications.

National is the leader in ceramic speaker driver technology for portable devices. The LM4962 and LM4953 integrated drivers allow manufacturers to create credit-card-thin handsets or add additional features to designs because the chips save space and reduce power consumption. This enables longer battery life and talk time.

Smart phones bring the convergence of PDA functionality, wireless connectivity and, increasingly, consumer audio to one full-featured device. The LM4935 allows handset designers to add the new audio features consumers demand. Its integration drives design simplicity and takes up a minimum amount of board space.
