Analog Devices Inc./Maxim Integrated MAX11410EVKIT#

Overview

MAX11410EVKIT# from Analog Devices is an evaluation kit for the MAX11410 24-bit delta-sigma ADC, configured as a universal analog input design board with integrated sensor front-end, isolated power supply, data isolator, and USB-to-SPI communication interface. It supports thermocouple (K-type), RTD (PT1000), and ±25mA current loop measurements with cold-junction compensation.

For engineers reviewing the MAX11410EVKIT# datasheet, MAX11410EVKIT# pinout, MAX11410EVKIT# application, or MAX11410EVKIT# equivalent, this kit enables rapid validation of precision industrial sensor signal chains - especially for temperature monitoring systems requiring simultaneous hot-junction, cold-junction, and reference temperature acquisition with pre-calibrated board-specific coefficients.

Technical Context

The MAX11410EVKIT# comprises two interlocked PCBs: an AFE board hosting the MAX11410 ADC, programmable gain instrumentation amplifier, reference voltage source, isolated DC-DC converter, and digital isolator; and a communication board centered on the MAXQ622 microcontroller for USB-to-SPI bridging. All jumpers are factory pre-installed per documented default positions.

It implements a complete isolated analog input channel supporting 7 selectable measurement modes - including K-type thermocouple, PT1000 RTD, ±20V differential, ±25mA loop, and ratiometric configurations - with automatic register configuration triggered by software radio-button selection in the provided MAX11410EVKit.exe GUI.

FAQ

What is the primary function of the MAX11410EVKIT#?

The MAX11410EVKIT# is an evaluation kit that demonstrates the full signal chain capability of the MAX11410 24-bit delta-sigma ADC. It integrates sensor conditioning, isolation, reference generation, and USB communication to enable immediate testing of thermocouple, RTD, voltage, and current inputs without custom hardware. The MAX11410EVKIT# includes pre-loaded firmware and GUI software for out-of-box operation.

Does the MAX11410EVKIT# support cold-junction compensation for thermocouples?

Yes, the MAX11410EVKIT# supports cold-junction compensation using a factory-installed PT1000 RTD connected to JP9. The included MAX11410EVKit.exe software automatically reads ambient temperature from the PT1000 and applies it to compute absolute thermocouple temperature. This dual-sensor measurement is implemented directly in the MAX11410EVKIT# hardware and firmware.

Which software is required to operate the MAX11410EVKIT#?

The MAX11410EVKIT# requires the Windows-based MAX11410EVKit.exe application, which provides a graphical interface with seven selectable measurement modes, real-time value display, and calibration file loading. No additional drivers or SDKs are needed beyond standard Windows USB CDC support; the MAXQ622 on the communication board handles all protocol translation internally.

Can the MAX11410EVKIT# be used with other ADCs or only the MAX11410?

The MAX11410EVKIT# is specifically designed for and exclusively compatible with the MAX11410 ADC. Its AFE board layout, jumper configurations (e.g., JP6, JP7, JP12), reference circuitry, and firmware are optimized for the MAX11410's register map, timing, and analog input structure. It does not support substitution with other ADCs, including other members of the MAX114xx family.

How are calibration files used with the MAX11410EVKIT#?

Calibration files (e.g., BRD1.MAX11410.txt) contain board-specific gain and offset coefficients generated during factory characterization. The MAX11410EVKit.exe GUI loads these .txt files via the "Load File" button under the Universal Input Measurement tab. Each file corresponds to a physical board revision, and selecting the correct one ensures accurate measurement across all input types supported by the MAX11410EVKIT#.
