Analog Devices Inc./Maxim Integrated MAX11616EVKIT+

Overview

MAX11616EVKIT+ from Maxim Integrated is an evaluation kit for the MAX11616 12-bit, 12-channel, I²C-compatible ADC operating from 4.5V to 5.5V supply, featuring 4.096V internal reference, 94.4ksps max sampling rate, and ultra-low 670µA active current. It enables rapid prototyping of battery-powered sensor acquisition systems in handheld medical instruments and remote monitoring nodes.

For engineers reviewing the MAX11616EVKIT+ datasheet, MAX11616EVKIT+ pinout, MAX11616EVKIT+ application, or MAX11616EVKIT+ equivalent, this kit provides validated hardware, firmware examples, and schematic-level design guidance to accelerate integration of the MAX11616 ADC into low-power, space-constrained embedded systems requiring precise analog signal digitization.

Technical Context

The MAX11616EVKIT+ implements a complete test platform for the MAX11616 ADC, including on-board voltage regulation, configurable analog input conditioning, I²C interface routing to host microcontrollers, and jumper-selectable reference modes (internal 4.096V or external). It supports all MAX11616 operating modes: unipolar/bipolar, single-ended/differential, and channel-scan with FIFO.

Hardware design includes precision decoupling (0.1µF ceramic + bulk capacitor), ESD-protected analog input terminals, level-shifted I²C signals compatible with 1.8V–5.5V controllers, and onboard LEDs for status indication. The board is optimized for accurate DC accuracy validation (±1 LSB INL/DNL) and dynamic performance measurement (70dB SINAD at 10kHz).

FAQ

What is the primary function of the MAX11616EVKIT+?

The MAX11616EVKIT+ is a fully assembled and tested evaluation kit for the MAX11616 12-bit, 12-channel I²C ADC. It provides immediate hardware access to all device features-including channel scanning, software-configurable unipolar/bipolar and single-ended/differential modes-and includes firmware examples, schematics, and layout files to validate system-level integration of the MAX11616 in real-world designs.

Does the MAX11616EVKIT+ support both internal and external reference configurations for the MAX11616?

Yes, the MAX11616EVKIT+ supports both reference modes. It defaults to the MAX11616's factory-configured 4.096V internal reference but includes a dedicated header (JREF) and jumper (JP1) to connect an external reference voltage between 1V and VDD. This allows direct validation of reference sensitivity, PSRR, and full-scale linearity under user-defined conditions.

Can the MAX11616EVKIT+ be used with microcontrollers operating at 1.8V logic levels?

Yes, the MAX11616EVKIT+ incorporates bidirectional I²C level shifters that translate between 1.8V–5.5V host controller logic and the MAX11616's 4.5V–5.5V interface. Pull-up resistors are placed on both sides of the shifter, ensuring reliable communication without external components-critical for validating interoperability with low-voltage MCUs.

What analog input protection features are implemented on the MAX11616EVKIT+?

The MAX11616EVKIT+ includes series 100Ω resistors and 0.1µF ceramic capacitors at each of the 12 analog input terminals to limit transient energy and reduce RF pickup. Input clamping diodes (integrated in the MAX11616) are supplemented by external TVS devices rated for ±15kV HBM ESD, enabling robust validation of analog front-end behavior under real-world field conditions.

Is the MAX11616EVKIT+ compatible with the MAX11617 ADC?

No-the MAX11616EVKIT+ is specifically designed for the MAX11616 and is not pin-compatible or functionally interchangeable with the MAX11617. While both share the same 16-pin QSOP package and 12-channel architecture, the MAX11617 uses a 2.048V internal reference and 2.7V–3.6V supply range; the MAX11616EVKIT+'s power regulation and reference circuitry are fixed for 4.5V–5.5V/4.096V operation and cannot safely accommodate the MAX11617.
