TIDA-00559 Reference Design

Texas Instruments

Combined Voltage/Current Output with Surge Protection Reference Design

Description

TIDA-00559 provides a universal analog output (AO) for industrial sensors and transmitters. It is based on a 16-bit DAC and uses a single output. This common output is user-configurable for 0 V to 10 V or for 4 ma to 20 mA. Usage in harsh industrial environments is addressed by a dedicated protection circuitry designed to withstand differential-mode surge pulses up to 1 kV / 40 Ω according to IEC61000-4-5. An isolated digital interface eases board configuration and evaluation.

Features
