[THAT-Corporation]

DESCRIPTION

The THAT300 Series ICs are large-geometry monolithic NPN and/or PNP transistor arrays which combine low noise, high speed and excellent parametric matching between devices of the same gender. The large geometries typically result in 25 Ω base spreading resistance for the PNP devices (30 Ω for the NPNs), producing 075 . nV√Hz voltage noise ( . 0 8 nV Hz for the NPNs). This makes the 300 Series an ideal choice for low-noise amplifier input stages.
