1.0 Benefits of the LPV321/358/324
Size.The small footprints of the LPV321/358/324 packages save space on printed circuit boards, and enable the design of smaller electronic products, such as cellular phones, pag- ers, or other portable systems. The low profile of the LPV321/358/324 make them possible to use in PCMCIA type III cards. Signal Integrity.Signals can pick up noise between the sig- nal source and the amplifier. By using a physically smaller amplifier package, the LPV321/358/324 can be placed closer to the signal source, reducing noise pickup and in- creasing signal integrity. Simplified Board Layout.These products help you to avoid using long pc traces in your pc board layout. This means that no additional components, such as capacitors and resistors, are needed to filter out the unwanted signals due to the inter- ference between the long pc traces. Low Supply Current.These devices will help you to maxi- mize battery life. They are ideal for battery powered sys- tems.
