Opamp is world’s smallest chip

National Semiconductor is claiming the world’s smallest chip, an opamp in a package just 2 by 2.1mm containing a sliver of silicon the “size of a flake of ground pepper”.
The LMV321 is designed for portable systems, occupying half the space of other opamps and operates at between 2.7 and 5V, extending battery life.
National says that the small size of the chip allows it to be placed closer to the signal source, which improves signal integrity. National said it used its BiCMOS process to make the chip.
