The LM3146 is a high voltage field effect transistor produced by National Semiconductor Corporation. It is packaged in a dual in-line package and features high voltage matched pairs of transistors, low noise figure and wide operating current range. It is widely used in various signal processing systems.
The LM3146 is a high voltage general purpose silicon NPN transistor array containing five transistors on a common monolithic substrate. Two of these transistors are internally connected to form a differentially-connected pair, providing inherent advantages of close electrical and thermal matching. The device is supplied in a 14-lead molded dual-in-line package for applications requiring a limited temperature range.
