Texas Instruments ADS5411EVM

Overview

ADS5411EVM from Texas Instruments is an evaluation module designed to characterize the ADS5411 - an 11-bit, 105-MSPS analog-to-digital converter (ADC) - under controlled analog input, clock, reference, and supply conditions. It supports transformer-coupled or differential amplifier-based single-ended-to-differential signal conditioning, buffered digital output via a 40-pin header, and flexible power provisioning including ±5 V for amplifier bias and 3.3 V/5 V for digital/analog domains.

For engineers reviewing the ADS5411EVM datasheet, ADS5411EVM pinout, ADS5411EVM application, or ADS5411EVM equivalent, this page delivers verified physical layout details, power configuration options, ADC interface topology, digital output buffering architecture, and jumper-controlled analog input path selection - all critical for lab validation and system-level ADC integration planning.

Technical Context

The ADS5411EVM implements dual analog input paths: one using Minicircuits ADT1-1WT 1:1 RF transformer (J11), the other using THS4503/THS4601 differential amplifiers (J10), with SJP3/SJP4 jumpers selecting source routing. Clock input is single-ended SMA-fed and converted to differential before reaching the ADS5411.

Digital outputs from the ADS5411 are level-shifted and driven by an SN74AVC16244 16-bit buffer (U2), then routed to J9 - a standard 40-pin IDC header with defined pin mapping for logic analyzer capture. Power delivery uses banana jacks (J1–J12) for isolated analog (5 V), digital (3.3 V), amplifier (±5 V), and buffer (3.3 V) rails, enabling performance optimization through supply separation.

FAQ

What is the primary function of the ADS5411EVM?

The ADS5411EVM is a hardware evaluation platform built to validate the electrical performance, timing behavior, and signal integrity of the ADS5411 - an 11-bit, 105-MSPS analog-to-digital converter. It provides configurable analog input conditioning, precise clock distribution, buffered parallel digital output, and modular power delivery, enabling engineers to measure SNR, SFDR, and ENOB under real-world operating conditions before integrating the ADS5411 into final systems.

Which ADC devices does the ADS5411EVM support?

The ADS5411EVM is explicitly designed for the ADS5411 (11-bit, 105-MSPS), but its schematic and layout also accommodate the pin-compatible ADS5423/24/33 family (14-bit, 80–105-MSPS). All supported devices share identical footprint, power pinout, and digital interface on U1; however, the ADS5411EVM documentation and default jumper settings are optimized for ADS5411 characterization.

How is analog input configured on the ADS5411EVM?

Analog input on the ADS5411EVM is configurable via two independent paths: transformer coupling (using ADT1-1WT at J11) or active differential amplification (using THS4503 and THS4601 at J10). Selection is made using surface-mount jumpers SJP3 and SJP4 - default configuration routes J11 (transformer) to AIN+ and J10-derived signal to AIN−, matching TI's recommended high-frequency layout.

What digital output interface does the ADS5411EVM provide?

The ADS5411EVM delivers parallel CMOS digital output from the ADS5411 through an SN74AVC16244 buffer (U2) to a 40-pin IDC header (J9). The header carries all 14 data bits (D0–D13), clock (CLK), overflow (OVR), data ready (DRY), driver supply (DRVDD), and ground pins - arranged per Table 2-1 in the SLWU020B User's Guide for direct logic analyzer connection without adapter.

What power supplies are required to operate the ADS5411EVM?

The ADS5411EVM requires up to four isolated DC supplies: +5 V (J3/J2) for ADC analog core, +3.3 V (J4/J6 and J1/J2) for digital I/O and output buffers, and ±5 V (J7/J8/J12) for the THS4503/THS4601 differential amplifiers. When using only transformer-coupled inputs, the ±5 V rails may be omitted; minimum viable configuration is +5 V AVDD and +3.3 V DVDD/DRVDD.
