Analog Devices Inc./Maxim Integrated MAX11615EVKIT+

Overview

MAX11615EVKIT+ from Maxim Integrated is an evaluation kit for the MAX11615 - a low-power, 12-bit, 8-channel I²C ADC with internal 2.048V reference, 94.4ksps sampling rate, and ultra-small 16-pin QSOP or WLP packaging. It enables rapid validation of sensor signal acquisition in battery-powered medical instruments, handheld test equipment, and solar-powered remote monitoring systems.

For engineers reviewing the MAX11615EVKIT+ datasheet, MAX11615EVKIT+ pinout, MAX11615EVKIT+ application, or MAX11615EVKIT+ equivalent, this kit provides full hardware access to the MAX11615's I²C interface, analog input channels (AIN0–AIN7), reference configuration options (internal/external), and power management modes (AutoShutdown™, low-throughput current <1µA).

Technical Context

The MAX11615EVKIT+ implements the MAX11615 ADC in a fully assembled, tested PCB layout with decoupling capacitors, pull-up resistors for SDA/SCL, jumper-selectable reference source (2.048V internal or external), and screw-terminal headers for analog inputs and power. It supports both single-ended (8-channel) and differential (4-channel) configurations via software register control.

It exposes all critical timing interfaces - including Fast Mode (400kHz) and High-Speed Mode (1.7MHz) I²C operation - and allows direct measurement of key performance metrics: INL ±1 LSB, DNL ±1 LSB, SINAD 70dB, THD –78dB, and full-power bandwidth of 3MHz - all verified across –40°C to +85°C.

FAQ

What is the primary function of the MAX11615EVKIT+?

The MAX11615EVKIT+ is an evaluation kit that provides a complete, ready-to-use hardware platform for testing and validating the MAX11615 12-bit, 8-channel I²C ADC. It includes all necessary circuitry - power regulation, I²C pull-ups, reference selection jumpers, and terminal blocks - enabling immediate connection to sensors and host microcontrollers without custom PCB design. The MAX11615EVKIT+ directly supports the MAX11615's full feature set, including AutoShutdown™, software-configurable unipolar/bipolar and single-ended/differential modes, and internal 2.048V reference operation.

Does the MAX11615EVKIT+ support both internal and external reference configurations?

Yes, the MAX11615EVKIT+ supports both internal and external reference configurations via on-board jumpers. By default, it uses the MAX11615's internal 2.048V reference, but users can disconnect it and apply an external reference voltage (1V to VDD) to the REF pin. The kit includes dedicated test points and routing to isolate the internal reference when an external source is selected, ensuring accurate calibration and minimizing noise coupling. This flexibility allows engineers to evaluate the MAX11615 under real-world reference conditions before final system integration.

Can the MAX11615EVKIT+ be used to verify timing compliance for High-Speed Mode I²C?

Yes, the MAX11615EVKIT+ is fully compatible with I²C High-Speed Mode (1.7MHz) as specified in the MAX11615 datasheet. Its PCB layout follows Maxim's recommended routing practices - including controlled trace lengths, proper grounding, and optimized pull-up resistor values - to meet timing requirements such as tHD,STA ≤160ns, tSU,DAT ≥10ns, and tRCL ≤80ns. Engineers can use the kit to validate signal integrity, clock synchronization, and data validity at 1.7MHz using standard logic analyzers or oscilloscopes connected to the SDA and SCL test points on the board.

What analog input configurations are accessible through the MAX11615EVKIT+?

The MAX11615EVKIT+ provides direct access to all eight analog input channels (AIN0–AIN7) via screw-terminal headers, supporting both single-ended and fully differential acquisition. In single-ended mode, each channel measures against ground; in differential mode, pairs (e.g., AIN0+/AIN1–) are configured via the MAX11615's setup register. The kit also exposes the AIN3/REF and AIN11/REF pins, allowing flexible reference routing and dual-purpose pin usage. All configurations are software-controlled - no hardware rework is needed to switch between modes.

Is the MAX11615EVKIT+ RoHS-compliant and suitable for production-level validation?

Yes, the MAX11615EVKIT+ is RoHS-compliant and built with lead(Pb)-free components, matching the environmental specifications of the underlying MAX11615 (denoted by the "+" suffix in part numbers like MAX11615EEE+). It uses production-grade PCB fabrication, 100% tested assemblies, and conforms to Maxim's extended temperature range (–40°C to +85°C) qualification. As such, it serves not only for early-stage prototyping but also for pre-production verification, including long-duration reliability testing, thermal profiling, and EMI susceptibility assessment in end-application environments.
