Preface Read This First About This Manual This manual describes the physical characteristics, functions, modes of op- eration, and configuration of the THS1030/31EVM evaluation module (EVM). How to Use This Manual Chapter 1 – Overview Chapter 2 – Physical Description Chapter 3 –...
Chapter 1 Overview This chapter gives a general overview of the THS1030/31EVM evaluation module (EVM), and describes some of the factors that must be considered in using this module. Topic Page Purpose ............
Purpose 1.1 Purpose The THS1030/31EVM evaluation module (EVM) provides a platform for evaluation of the THS1030 and THS1031 10-bit analog-to-digital converters (ADC) under various signal, reference, and supply conditions. Unless stated explicitly, the functionality described in this user’s guide applies to both THS1030 and THS1031 devices.
EVM components. 1.4 THS1030/31EVM Operational Procedure The THS1030/31EVM provides a flexible means of evaluating the THS1030 and THS1031 in a number of modes of operation. These are described more fully in chapter 4. The following basic setup procedure can be used as a board-...
Chapter 2 Physical Description This chapter describes the physical characteristics and PCB layout of the EVM, and lists the components used on the module. Topic Page PCB Layout ..........Parts List .
PCB Layout 2.1 PCB Layout The EVM is constructed on a 4-layer, 151-mm (5.94 ) 115-mm (4.54 ), 1.57-mm (0.062 ) thick PCB using FR-4 material. Figures 2–1 through 2–6 show the individual layers. Figure 2–1. Silk Top...

Chapter 3 Circuit Description This chapter contains the EVM schematic diagram and discusses the various functions on the EVM. Topic Page Schematic Diagram ......... . . Circuit Function .
Circuit Function 74AHC14 hex inverter IC (U4), then it should be ac-coupled through C24, with its dc level trimmed using potentiometer P1 if necessary. 3.2.2 Clock Options The EVM provides flexibility as to the source of the ADC conversion clock: this can come from an external source as described above, or from a crystal-oscil- lator module when U3 is populated with a standard DIL14 HCMOS.
