Mixed module (AI,AO,DI,DO)

Block diagram

Overview

Our integrated circuits and reference designs enable you to build a mixed module using a combination of analog input (AI), analog output (AO), digital input (DI) and digital output (DO).

Design requirements

Mixed module (AI, AO, DI, DO) designs often require:

  • Highly efficient isolated power supply with advanced protection and diagnostics.
  • Precision signal chain for input filtering.
  • Driving capabilities at 24-V nominal voltage.
