Alfa

Transistor - AS3046, Array of 5, Matched Pair, 14-Pin DIP, NPN
The AS3046 is Alfa’s version of the CA3046 (LM3046) IC. The AS3046 consists of five general purpose silicon NPN transistors on a common monolithic substrate. Two of the transistors are internally connected to form a differentially-connected pair. The transistors are well suited to a wide variety of applications in low power systems. They may be used as discrete transistors in conventional circuits however, in addition, they provide the very significant inherent integrated circuit advantages of close electrical and thermal matching. The AS3046 is available in a 14-pin DIP package. Features
  • Matched pair of npn transistors
  • VBE matched less than ±1 mV
  • 5 general purpose monolithic transistors
  • Wide operating current range

Applications
  • Filters
  • Custom designed differential amplifiers
  • Temperature compensated amplifiers

Integrated Circuit - AS3360, Dual VCA, Alfa, 14-Pin Dip
The AS3360 is Alfa’s version of the CEM3360 IC. The AS3360 is a dual general purpose voltage controlled transconductor intended for such applications as voltage controlled amplifiers, filters, and waveform generators. Each transconductor independently provides both linear and exponential control scaling over greater than a 100 dB range. Complete with virtual ground summing inputs, wide voltage compliance current outputs, and control inputs referenced to ground, the AS3360 requires exceptionally few external components and is extremely easy to use. Because of its inherent ultra-low control feedthrough, no trimming is required.
