Analog Devices Inc./Maxim Integrated MAX11103EVKIT+

Overview

MAX11103EVKIT+ from Maxim Integrated is an evaluation kit for the MAX11103 - a 12-bit, 3Msps, dual-channel, single-ended successive-approximation ADC with external reference input, 2.2V–3.6V supply, and SPI/QSPI/MICROWIRE-compatible 3-wire serial interface. It supports portable data acquisition and battery-powered medical instrumentation requiring high dynamic range (72dB SNR) and low power (5.2mW at 3Msps).

For engineers reviewing the MAX11103EVKIT+ datasheet, MAX11103EVKIT+ pinout, MAX11103EVKIT+ application, or MAX11103EVKIT+ equivalent, this kit enables rapid validation of MAX11103 performance in real-world signal chains - including full-speed timing compliance, reference voltage sensitivity, channel-to-channel matching (±0.05 LSB gain), and low-noise analog front-end integration.

Technical Context

The MAX11103EVKIT+ provides a complete, ready-to-run platform to evaluate the MAX11103 ADC's 3Msps throughput, 12-bit resolution, and dual analog inputs (AIN1/AIN2) with internal 2:1 MUX routing. It implements the device's full feature set: external reference input (REF), independent digital I/O supply (OVDD), and fast wake-up from 1.3µA power-down mode.

Designed for direct connection to host microcontrollers via standard SPI, the kit includes on-board decoupling, precision reference options, and configurable analog input paths - enabling accurate measurement of key specs including aperture jitter (15ps), acquisition time (52ns), and SINAD (72dB typical at 1MHz input).

FAQ

What is the primary function of the MAX11103EVKIT+?

The MAX11103EVKIT+ is a fully assembled and tested evaluation platform for the MAX11103 12-bit, 3Msps dual-channel SAR ADC. It allows engineers to validate timing, noise, linearity, and interface behavior of the MAX11103 in real circuit conditions - including external reference operation, dual-input switching, and low-power mode transitions - without custom PCB design.

Does the MAX11103EVKIT+ support both MAX11102 and MAX11103 devices?

No - the MAX11103EVKIT+ is specifically configured and validated for the MAX11103 (3Msps variant). While physically compatible with the pinout of the MAX11102 (2Msps), its timing-critical layout, clocking, and firmware are optimized for 3Msps operation and full-speed characterization of the MAX11103's 48MHz SCLK interface and 260ns conversion time.

Can the MAX11103EVKIT+ be used to evaluate external reference performance?

Yes - the MAX11103EVKIT+ includes dedicated REF input terminals, onboard low-noise reference buffer circuitry, and jumper-selectable reference sources (including external SMA input), enabling direct measurement of MAX11103 reference rejection (0.7 LSB/V), INL/DNL vs. VREF, and SNR degradation across 1V–3.6V reference voltages.

What host interface protocols does the MAX11103EVKIT+ support out-of-the-box?

The MAX11103EVKIT+ supports direct connection to host controllers via standard 3-wire SPI, QSPI, or MICROWIRE interfaces. It requires no protocol translation or FPGA logic - the onboard MAX11103 operates natively with CS, SCLK, and DOUT signals, and includes CHSEL for analog input channel selection during evaluation.

Is software provided with the MAX11103EVKIT+?

Yes - the MAX11103EVKIT+ ships with Maxim's EV-kit GUI software (Windows-based), supporting real-time waveform capture, FFT analysis, histogram generation, and DC accuracy testing. The GUI communicates via USB-to-SPI bridge and includes preconfigured scripts for measuring SNR, SINAD, THD, and channel matching per the MAX11103 datasheet test conditions.
