Integrerade kretsar


Integrerade kretsar ("IC-kretsar") är kretsar där en viss logisk eller analog funktion realiserats genom att kombinera ett antal transistorer på samma kiselbricka. Detta gör att samma funktion kan realiseras på mindre yta än om den realiserats med diskreta transistorer.

Det finns huvudsakligen två typer av kapsling för integrerade kretsar; hålmonterade (DIP-) och ytmonterade (SO-). De flesta kretsar finns i både hålmonterat och ytmonterat utförande.

  AD633JNZ DIP-8 Analog multiplikator
The AD633 is a complete four-quadrant multiplier offered in low cost 8-lead plastic packages. The result is a product that is cost effective and easy to apply. No external components or expensive user calibration are required to apply the AD633. Monolithic construction and laser calibration make the device stable and reliable. High (10 M?) input resistances make signal source loading negligible. Power supply voltages can range from ± 8 V to ± 18 V. The internal scaling voltage is generated by a stable Zener diode; multiplier accuracy is essentially supply insensitive. Features Total Error within 2% of FS Differential High Impedance X and Y Inputs High Impedance Unity-Gain Summing Input Laser-Trimmed 10 V Scaling Reference Applications Multiplication, Division, Squaring Modulation/Demodulation, Phase Detection Voltage Controlled Amplifiers/Attenuators/Filters
