DESCRIPTION
The THAT300 Series ICs are large-geometry
monolithic NPN and/or PNP transistor arrays which
combine low noise, high speed and excellent para-
metric matching between devices of the same gender.
The large geometries typically result in 25
W base
spreading resistance for the PNP devices (30
W for
the NPNs), producing 075
.
nV Hz voltage noise
(.
08
nV
Hz for the NPNs). This makes the 300
Series an ideal choice for low-noise amplifier input
stages.
Fabricated on a Complementary Bipolar Dielec-
trically Isolated process, each transistor is electri-
cally isolated from the others by a layer of insulating
oxide. The resulting low collector-to-substrate capac-
itance produces a typical NPN f
T
of 350 MHz,
325 MHz for the PNPs. This delivers ac performance
similar to discrete 2N3904- and 2N3906-class de-
vices. Dielectric isolation also minimizes crosstalk
and provides complete DC isolation.
Substrate biasing is not required for normal op-
eration, though the substrate should be grounded to
optimize speed and minimize inter-device crosstalk.
The monolithic construction assures excellent pa-
rameter matching and tracking over temperature.
