The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.

This page will guide you through the process of setting up and using the NAFExx388- EVB board.

2.1 Board Features

  • Eight input SW configurable AI-AFE
  • Easy-to-use GUI-based software demonstrates the capabilities of the NAFExx388
  • Onboard transformer to provide DC-DC power supply (+3.3 V, ±15 V) to NAFExx388
  • Convenient test points for easy scope measurements and signal access
  • USB interface to the host PC

2.2 Board Description

The NAFExx388-EVB evaluation board features a highly configurable, industrial-grade, multichannel AI-AFE that meets high-precision measurement requirements. The device is composed of a low-leakage, high-voltage multiplexer, low-offset drift buffers, a low noise and drift PGA, a precision 24-bit sigma delta (ADC) and low-drift voltage reference.

3.1 Configure the Hardware

The NAFExx388 evaluation kit includes the NAFExx388 evaluation board, an OM13098 (LPC54628) evaluation board, and a USB cable.

To set up the hardware, do the following:

  1. Firmly connect the NAFExx388 (AFE) evaluation board to the LPC54628 (microcontroller) evaluation board using the Arduino connectors.
  2. To connect both boards, slide J15, J18, J19, and J22 male connectors at the bottom side of the NAFExx388 (AFE) evaluation board into the appropriate female connectors on the LPC54628 (microcontroller) evaluation board.
  3. Apply AVDD/DVDD = 3.75 V on J9, HVDD = +15.4 V on J10, and HVSS = -15.4 V on J11 banana jack connectors and turn on the power supply.
  4. Connect USB to µUSB cable between USB port of the computer and J2 (µ USB) port of LPC54628 evaluation board.
