75 nV/ √Hz (PNP) º 0.
8 nV/ √Hz (NPN) • High Speed º fT = 350 MHz (NPN) º fT = 325 MHz (PNP) • 500 μV matching between devices • Dielectrically Isolated for low crosstalk and high DC isolation • 36V VCEO Low-Noise Matched Transistor Array ICs THAT 300 Series APPLICATIONS • Low Noise Front Ends • Microphone Preamplifiers • Log/Antilog Amplifiers • Current Sources • Current Mirrors • Multipliers Description 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 25 Ω for the PNP devices (30 Ω for the low-gain...
