1.1 Introduction

The ADS1282 is a high-performance, single-chip, delta-sigma analog-to-digital converter (ADC) with an integrated, low-noise programmable gain amplifier (PGA) and two-channel input multiplexer (mux). The ADS1282 is an excellent choice for the demanding needs of energy exploration and seismic monitoring environments. The PHI board primarily serves three functions:

  • Provides a communication interface from the EVM to the computer through a USB port
  • Provides the digital input and output signals necessary to communicate with the ADS1282
  • Supplies power to all active circuitry on the ADS1282EVM board

This user's guide describes the characteristics, operation, and use of the ADS1282 evaluation module (EVM). The ADS1282EVM enables the evaluation of the device through a USB interface. This user's guide includes complete circuit descriptions, schematic diagrams, and a bill of materials. Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the ADS1282EVM.
