EVM IMPORTANT NOTICE

Texas Instruments (TI) provides the enclosed product(s) under the following conditions:

This evaluation kit being sold by TI is intended for use for ENGINEERING DEVELOPMENT OR EVALUATION

PURPOSES ONLY and is not considered by TI to be fit for commercial use. As such, the goods being provided

may not be complete in terms of required design-, marketing-, and/or manufacturing-related protective

considerations, including product safety measures typically found in the end product incorporating the goods.

As a prototype, this product does not fall within the scope of the European Union directive on electromagnetic

compatibility and therefore may not meet the technical requirements of the directive.

Should this evaluation kit not meet the specifications indicated in the EVM User’s Guide, the kit may be returned

within 30 days from the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE

WARRANTY MADE BY SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED,

IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY

PARTICULAR PURPOSE.

EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 8 V to 40 V and the output

voltage range of 0 V and 5 V.

Exceeding the specified input range may cause unexpected operation and/or irreversible

damage to the EVM. If there are questions concerning the input range, please contact a TI

field representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or

possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to

connecting any load to the EVM output. If there is uncertainty as to the load specification,

please contact a TI field representative.

During normal operation, some circuit components may have case temperatures greater than

xxx°C. The EVM is designed to operate properly with certain components above xxx°C as

long as the input and output ranges are maintained. These components include but are not

limited to linear regulators, switching transistors, pass transistors, and current sense

resistors. These types of devices can be identified using the EVM schematic located in the

EVM User’s Guide. When placing measurement probes near these devices during operation,

please be aware that these devices may be very warm to the touch.

1.1 Features

-Evaluation Board featuring the ADS1605 ADC (order ADS1605 EVM) or

ADS1606 ADC (order ADS1606 EVM).

-On-board reference, with recommended buffer circuitry

-On-board signal conditioning.

-Basic system-level logic decoding.

1.2 Introduction

The ADS1605 EVM is a high speed high resolution delta sigma (∆Σ) analog-to-

digital converter. It features a data rate of 5 MSPS, a bandwidth (−3 dB) of

2.45 MHz and a passband ripple of less than ±0.0025 dB.

The evaluation module (EVM) is a stand-alone, full-featured system that offers

data sheet performance. Additionally, the EVM conforms to a common

electrical and mechanical pinout for analog I/O, digital I/O and power, enabling

the EVM to be quickly adapted to various host platforms.

Typical performance of the ADS1605 EVM is shown by the FFT plot in

Figure 1−1.

1.3 Analog Interface

The analog interface consists of the following subsections:

-Analog Input

-External reference

-Modulator clock

Alterations to the analog interface are achieved by various jumpers, the

function of each is summarized in Table 1−1.
