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  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%.Watch a TIDA-00231 overview video on the Isolated DC/DC Converter reference design NOW
