LM3146 High Voltage Transistor Array
General Description
The LM3146 consistsoffive high voltage general purpose
silicon NPN transistorsona common monolithic substrate.
Twoofthe transistorsare internally connectedto forma
differentially-connected pair. The transistorsarewell suiteda wide varietyof applicationsinlow power systeminthe through VHF range. They maybe usedas discrete tran-
sistorsin conventional circuits however,in addition, they
providethe very significant inherent integrated circuitad-
vantagesof close electrical and thermal matching. The
LM3146is suppliedina 14-lead molded dual-in-line pack-
agefor applications requiring onlya limited temperature
range.
Features High voltage matched pairsof transistors, VBE matched mV, input offset current2mA maxatICe 1mA Five general purpose monolithic transistors Operation fromdcto 120 MHz Wide operating current range Low noise figure 3.2dBtypat1 kHz
Applications General useinall typesof signal processing systems
operating anywhereinthe frequency range fromdcto
