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 resistance, producing 0.
75 nV Hz voltage noise.
This makes these parts an excellent choice for low-noise amplifier i...
