As a result, they exhibit geometry, 4-transistor, monolithic NPN and/or PNP inter-device crosstalk and DC isolation similar to arrays. They exhibit both high speed and low noise, that of discrete transistors. The resulting low with excellent parameter matching between transis- collector-to-substrate capacitance produces a typical tors of the same gender. Typical base-spreading NPN f of 350 MHz (325 MHz for the PNPs). T resistance is 25 for the PNP devices (30 for the Substrate biasing is not required for normal opera- low-gain NPNs), so their resulting voltage noise is tion, though the substrate should be ac-grounded to under 1 nV/Hz. This makes the 300 series ideally optimize speed and minimize crosstalk. suited for low-noise amplifier input stages, log ampli- fiers, and many other applications.
