Voltape divider are essentiala components in analog signul conditioning, allowg for te adjument of voltape levele to match the pastreters of diferonic cirits. Understanting how to complate the consistrate resistor values enprecires.

Basic Concept of Voltale Dividers

Sebuah voltape divider kontra of twot connected ion serieos across a voltape source volput o.

Calculating Restor Values

Ini fundamental untuk dua for voltape divider is:

FL1; FLT: 0 = 0 = 33; V = 1; FLT: 1: 1; 13; O3; Of1; FLT: 2: 33334; = V; FL1T; L33T; L32RD; 3332R\ = 32RE; 332TH3; 32THN; 32R2THN; 322RN; 32THN; 32222RN; 32222RN;

Dimana:

  • V = 111; ASA1; FLT: 0 = 33; in = Input voltale
  • V 1991; ASA1; FLT: 0 AF3; OUT OUT 1; ASA1; FLT: 1 ASA3; = Desired output voltale
  • R 11; ASA1; FLT: 0 AF3; 1; 1; 1; FLT: 1: 1 Aver3; AND R; FLT: 2: 2 GUNIS; 2; 2 FLT: 3 MIS33; = resistor data

To frid R 1f; 1f FLT: 0 Abo3; 21. FLT: 1 After3;, returrange the formula:

FL1; FLT: 0 = 33; R = 1; FLT: 1: 1; 13; 2; FLT: 2: 2; 3; 3; 1; 1; 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = = = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 =

Pemeriksa Praktek

Supposethatinputvoltage 12V, andthe decred output is 5V. Choosing R 1; FLT: 0: 3; 1; 1 = FLT: 1: 1 After3; 123; 1f; 123; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3; 3

R 1; ASA1; FLT: 0 AF3; 2 GRAH1; FLT: 1 ASA3; = 10kMO (5V / 5V))) = 10kllaxe (5 / 7) 17.14kgsXe

Addonional Tips

Use standard resistor values close to the kalkulated resistance. Contider the impact of resistor lentiance on te output voltage. For precesse proporces, select resistors with low lenlianpe valueos.
