The THAT340S14-U is a low-noise, matched bipolar transistor array featuring two matched NPN transistors and two matched PNP transistors arranged in a monolithic configuration. These transistors are designed with large geometry for high speed and excellent parameter matching, making them ideal for low-noise amplifier input stages, log amplifiers, and similar applications. Fabricated using a dielectrically isolated, complementary bipolar process, each transistor is electrically insulated from the others by an insulating oxide layer, providing low crosstalk and high DC isolation comparable to discrete transistors. The device does not require substrate biasing for normal operation; however, grounding the substrate can enhance speed and reduce crosstalk. It offers high-speed performance with low voltage noise, 500 microvolt matching between devices, and is suitable for audio, power management, and industrial uses. Please note that due to high market demand, lead times may be extended, and delivery dates can fluctuate. The product is not eligible for discounts.
