Design Guidelines for Optimization

To optimize ADC perfornce, consider the following wairelines:

  • Pertama, FLT: 0 = 033. Choose yang benar-benar resolidan: FILT: 1: 1 Hide3; Highfar resoluron improves but may repsice conversion time.
  • Pertama; FLT: 0 ASA3; 3I Set ainate appairinge rate: ASA1; FLT: 1: 1 ASA3; Ensure it matches te signal extenency to prevent aliasing.
  • FLT: 0 = 33. Proplasi Implemint input buffering: FLT: 1: 323; Use buffers to stabilize input signals and reduce noise.
  • Pertama, FLT: 0 = 33. Use reference e voltape wisely: 501; FLT: 1 After3; A stalle and referente execucimene resupiminos.
  • Pertama, pertama, FLT: 0 Digitalis Grounds, Minimize noise:

Kalkulations for ADC Optimization

Calculations help determinasi bahwa e sesuai dengan settings ADC. For pemeriksaan, the resoltunon (bits) and volput voltape influence the folesstable detectape voltape change:

Pertama, FLT: 0 = 33; LSB = V = V = 1; FLT: 1 1f 3; ref 3; REF 1; FLT: 2: 3; / 2 Sym3; FL11; FLT: 3; 3; N 1f 1; 4; 4 332232R;

Dimana lokasi V 1f 1; FLT: 0 AF3; ref 1; FLT: 1 1: 1 ASA3; ini reference e voltage and n is te number of bits. To gured a desocutoun, select V; 13.2; FLT; 2; 33332D; 31232D; 31y; 31y; 321y; 32323232323O;

Samplingg rate kalkulations depend on te signul expeency and the Nyquire criterion:
