Software Configurable Universal Analog Output AFE
The NAFE33350 is a software-configurable universal output (AO) analog front end (AFE) that meets high-precision control requirements of industrial-grade applications. The AO-AFE integrates the following components.
- A precision 18-bit digital-to-analog converter (DAC)
- A low-drift voltage reference
- Low-offset-drift buffers
- A 65 V input-protection circuit for electromagnetic compatibility (EMC) and miswiring scenarios
For open circuit and short-circuit detection, the output stage includes built-in diagnostic and protection circuitry.
The AO AFE is suitable for programmable logic controllers (PLC), analog output modules, isolated industrial control systems and process control.
