This single-channel, power-isolated, analog output module reference design delivers current and voltage outputs using the highly-integrated DAC8771 digital-to-analog converter (DAC). The high integration of the DAC8771 coupled with the LM25180 primary-side regulated flyback converter lead to a compact, isolated design with 52-mm × 40-mm board dimensions and a maximum component height of 4 mm. Additionally, the design features external circuitry to provide transient protection for electromagnetic interference (EMI) and electromagnetic compatibility (EMC).
Features
- Isolated analog output for factory automation and control
