Description

THAT140 is a quad, large-geometry monolithic NPN/PNP transistor array which combines low noise, high speed and excellent parametric matching. The large geometries THAT140 typically result in 25 base spreading resistance for the PNP devices (30 for the NPNs), producing 0.75 nV/ Hz voltage noise (0.8 nV/Hz for the NPNs). This makes these parts an ideal choice for low-noise amplifier input stages.

Fabricated on a Complementary Bipolar Dielectrically Isolated process, all four transistors are electrically isolated from each other by a layer of oxide.

The resulting low collector-to-substrate capacitance THAT140 produces a typical NPN ft of 350 MHz, 325 Mhz for the PNPs. This delivers AC performance similar to discrete 2N3904- and 2N3906-class devices.Dielectric isolation also minimizes crosstalk and provides complete DC isolation.

Substrate biasing is not required for normal operation, though the substrate should be grounded to optimize speed. The monolithic construction assures excellent parameter matching and tracking over temperature.
