Mike Polacek Quotations

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.

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.

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.
