4-transistor, monolithic NPN and/or PNP arrays ex-

hibiting both high speed and low noise, with excel-

lent parameter matching between transistors of the

same

resistances of 25 ohms for the PNP devices

(30 ohms for the NPNs), their resulting low voltage

noise of under 1 nV/root-Hz makes the 300 series

ideally suited for low-noise amplifier input stages,

tions used in conventional arrays) and exhibit

inter-device crosstalk and DC isolation similar to

that expected from discrete transistors. The result-

ing low collector-to-substrate capacitance produces

a typical NPN f

PNPs). Substrate biasing is not required for normal

operation, though the substrate should be grounded

to optimize speed and minimize crosstalk.
