NXP Semiconductors NAFE33350 Software Configurable Universal AO AFE
NXP Semiconductors NAFE33350 Software Configurable Universal Analog Output AFE helps PLC, remote I/O, building I/O, and industrial HMI systems deliver precise analog voltage and current outputs. It is a software-configurable analog output (AO) analog front end (AFE) with an 18-bit digital-to-analog converter (DAC), a low-drift voltage reference, and low-offset buffers.
The NXP Semiconductors NAFE33350 provides precise control over the ±12.5V and ±25mA output ranges for industrial-grade applications. Built-in open-circuit and short-circuit diagnostics, 65V input protection, and operation from -40°C to 125°C support isolated industrial control and process control systems.
