AC analog input module

High precision data acquisition integrated circuits and reference designs


Protection relays are designed based on the application type – generator protection, transformer protection, motor protection, feeder protection, transmission and distribution protection etc. Relays that are modular are designed to have multiple functional modules. The AC analog input module performs the data acquisition function that consists of various sensors to measure voltage and current, signal conditioning circuitry, a data acquisition system, and a host interface. TI reference designs and ICs help:

  • Showcase accurate, high speed conversion of voltage (110 Vrms or 220 Vrms) or current (I nominal: 1A or 5A) into digital equivalent
  • Highlight trade-offs for various data acquisition architectures with and without isolation
  • Cover wide dynamic range in noisy environments with temperature variations using high performance, integration and flexibility
