ADS41xx/58B18EVM

1 Overview

This evaluation module (EVM) user's guide gives an overview of the EVM and provides a general

description of the features and functions to be considered while using this module.

This EVM user's guide applies to multiple EVMs:

• ADS41xx family:

– ADS4126, ADS4146, ADS4128, ADS4129, ADS4149, ADS41B29, ADS41B49, ADS58B18

1.1 Purpose

The ADS41xx/58B18 EVM provides a platform for evaluating the analog-to-digital converter (ADC) under

various signal, clock, reference, and power supply conditions. Use this document in combination with the

EVM schematic diagram supplied.

1.2 EVM Quick-Start Procedure

The ADS41xx/58B18EVM provides numerous options for providing clock, input frequency, and power to

the ADC under evaluation. The quick-start procedure describes how to quickly get initial results using the

default configuration of the EVM as it was shipped. The EVM can be put back to default configuration by

setting all jumpers with the default values as described in Table 1. The default configuration of the EVM is

for single-ended signals into the analog input and clock input. These signals are converted from single-

ended to differential onboard with the use of transformers. The default configuration for the power supply

is to provide a single 3.3-V supply to the red banana jack J16, PWR_IN. The default configuration for the

EVM is to control the modes of operation by jumper settings for parallel input control pins rather than

serial SPI control of the register space. The other modes of operation of the EVM are described in the

latter sections of this document.

CAUTION

Voltage Limits: Exceeding the maximum input voltages can damage EVM

components. Undervoltage can cause improper operation of some or all of the

EVM components.

A quick-setup procedure for the default configuration of the ADS41xx/58B18EVM follows:.

1. Verify all jumper settings against the schematic jumper list in Table 1.
