THAT340S14中文资料Low-Noise Matched Transistor Arrays数据手册THAT规格书

描述 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 25Ω for the PNP devices (30Ω for the low-gain 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. The four-NPN transistor array is available in versions selected for hfe with minimums of 150 (300A) or 300 (300B).
