型號(hào)： THAT320P14-U

品牌： THAT

類別： 集成電路

封裝： DIP

描述： The THAT320P14-U is a low-noise matched Bipolar Transistor Array with large geometry monolithic 4-matched PNP transistors configuration. It exhibits both high speed and low noise with excellent parameter matching between transistors of the same gender. The base-spreading resistance is 25R for the PNP devices, so their resulting voltage noise is under 1nV/√Hz. The device is ideally suited for low-noise amplifier input stages, log amplifiers and many other applications. Fabricated in a dielectrically isolated, complementary bipolar process, each transistor is electrically insulated from the others by a layer of insulating oxide. It exhibits inter-device crosstalk and DC isolation similar to that of discrete transistors. The resulting low collector-to-substrate capacitance produces a PNP fT of 325MHz. Substrate biasing is not required for normal operation, though the substrate should be ac-grounded to optimize speed and minimize crosstalk. . 4-matched PNP transistors with hfe of 150 . Low voltage noise . High speed . 500μV matching between devices . Dielectrically isolated for low crosstalk and high DC isolation
