1.1 Introduction

This user's guide describes the characteristics, operation, and use of the AMC038XEVM. This evaluation module (EVM) is an evaluation and development kit for evaluating the precision, isolated amplifiers with an integrated, high-voltage resistive divider at the input. These devices are available with the integrated, high-voltage resistive dividers configured to accommodate high voltage systems. The three output options available for these devices are differential output, single-ended ratiometric (configurable gain) output, and digital modulator output.

Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the AMC038XEVM. This document includes how to set up the EVM, the printed circuit board (PCB) layout, schematics, and bill of materials (BOM).

The following pin and net names are synonymous or interconnected:

  • AVDD = VDD1 = J1.2
  • DVDD = VDD2 = J2.2
  • VOUTP = VOUT = CLKIN = J3.2 = TP4
  • VOUTN = VREF = DOUT = J3.1 = TP5
  • AGND = GND1 = J1.1 = TP1
  • DGND = GND2 = J2.1 = TP2 = TP3
  • VSNS = TP6
  • HVIN = VHV1 = turret connector
