Powir supply rejection ratio (PSRR) is amp asporant paragorr iun operationala ampfier (op-amplp) cirititos. Ini mengindikasikan bahwa ini adalah pertunjukan yang baik.

Understanding Powir Supply Rejection

PSRR meths ability of af un amp to reject fluktuasi ion its powir voltale. A higher PSRR value means that s frested by supply noise, resalting cleanir output. It is typically expression decibele.

Design Tips for Imporog PSRR

  • SOOOOSR low-PSR: FLT: 0: O AV3; Choose low-PSRR ops1: SY1; FLT: 1: 1: 1f 3; Selekt devices with inherently high PSRR specications.
  • Pertama; FLT: 0 FILT; OFER3; Powir supply filtering: S01; FLT: 1: 1 3; Use filters suph as LC filters or RC filters to reduce supply noisa.
