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
