NXP NAFE33352-UIOM AIO AFE Arduino® Shield Evaluation Board

Introduction

The NXP Semiconductors NAFE33352-UIOM is an Arduino-compatible evaluation shield for exploring the capabilities of the NAFE33352 industrial universal analog input and output front-end. It provides a practical development platform for testing precision sensor measurement and analog control functions with compatible NXP FRDM microcontroller boards.

Part Description

The NAFE33352-UIOM evaluation board is built around the NAFE33352 configurable analog front-end device. It is intended for industrial signal-conditioning applications that require flexible measurement inputs and accurate analog outputs.

The board supports a range of common industrial input types, including voltage, current, resistance temperature detector (RTD), and thermocouple signals. This flexibility allows engineers to evaluate the same front-end platform with multiple sensor technologies and signal ranges.

In addition to analog measurement functions, the board supports analog output generation up to ±12.5 V and ±25 mA. These output capabilities are useful for evaluating control and actuator interfaces, including common voltage and current-loop signaling methods.
