Description

TIDA-00231 is a reference design for an industrial Programmable Logic Controller (PLC) analog output module. The design provides a unique power saving solution for a digital-to-analog converter (DAC)-based analog current output module with an adaptive power supply. This adaptive power supply dynamically regulates the AVDD supply of the DAC and limits power losses to < 50mW for typical load resistance of > 300Ω. The analog output can source current up to 24mA. This reference design includes the necessary on-board protection circuit and has been tested to IEC61000-4 standard EFT, ESD, and surge requirements with IO Controller platforms. The protection circuitry does not negatively affect the design and Test results showed typical unadjusted errors were less than 0.2% FSR and calibrated accuracy is 0.05%.

Features
  • 16 bit user configurable analog current output
  • Accuracy
    o Un-calibrated better than  ±0.2% FSR at 25 °C
    o Calibrated better than  ±0.05% FSR at 25 °C
  • Adaptive Power Supply reduces system power dissipation- power losses across FET are limited to < 50mW for typical load resistance > 300Ω
  • Reverse voltage protection for analog output
  • On-board isolated Flybuck™ power supply with inrush current protection
  • Designed to comply with IEC61000-4 Standards for ESD, EFT, and Surge
