(Note: THAT300 pictured.) The THAT 300, 320 and 340 are large geometry, 4-transistor,
monolithic NPN and/or PNP arrays. They exhibit both high speed and low
noise, with excellent parameter matching between transistors of the same
gender. Typical base-spreading resistance is 25Ω
for the PNP devices (30Ω for the NPNs), so their resulting
voltage noise is under 1 nV/√Hz. This makes the 300 series ideally
suited for low-noise amplifier input stages, log amplifiers, and many
other applications.
