DESCRIPTION
THAT120 is a quad, large-geometry monolithic
PNP transistor array which combines low noise, high
speed and excellent parametric matching. The large
geometry typically results in 25 W base spreading re-
sistance, producing 0.75 nV Hz voltage noise. This
makes these parts an excellent choice for low-noise
amplifier input stages.
Fabricated on a Complementary Bipolar Dielec-
trically Isolated process, all four transistors are elec-
trically isolated from each other by a layer of oxide.
The resulting low collector-to-substrate capacitance
produces a typical ft of 325 MHz, for AC perfor-
mance similar to 2N3906-class devices. The dielec-
tric isolation also minimizes crosstalk and provides
complete DC isolation.
Substrate biasing is not required for normal oper-
ation, though the substrate should be grounded to
optimize speed. The one-chip construction assures
excellent parameter matching and tracking over tem-
perature.
