Analog Devices Inc./Maxim Integrated MAX11046EVKIT+

Overview

MAX11046EVKIT+ from Maxim Integrated is an evaluation kit for the MAX11046 8-channel, 16-bit, simultaneous-sampling analog-to-digital converter. It supports ±5V input range, 250ksps per channel throughput, and features independent track-and-hold circuitry with 100ps channel-to-channel T/H matching. The kit enables rapid validation of high-precision data acquisition in power-grid protection and multiphase motor control systems.

For engineers reviewing the MAX11046EVKIT+ datasheet, MAX11046EVKIT+ pinout, MAX11046EVKIT+ application, or MAX11046EVKIT+ equivalent, this kit provides full hardware access to the MAX11046 ADC's parallel interface (DB0–DB15), CONVST/EOC timing signals, REFIO reference path, and configurable digital supply (2.7V–5.25V) - essential for evaluating simultaneous sampling accuracy, crosstalk, and system-level timing margins.

Technical Context

The MAX11046EVKIT+ implements the full signal chain of the MAX11046 ADC, including its 8-channel analog front-end with ±20mA input clamps, internal 4.096V reference, and 20MHz bidirectional parallel interface. It supports both internal clock operation and external trigger synchronization via CONVST.

Designed for direct interfacing with host processors or FPGAs, the kit routes all critical ADC pins-including AVDD (4.75V–5.25V), DVDD (2.7V–5.25V), AGND/DGND separation, and RDC decoupling-according to Maxim's layout guidelines for low-noise, high-channel-count sampling.

FAQ

What is the primary function of the MAX11046EVKIT+?

The MAX11046EVKIT+ is a fully assembled and tested evaluation platform for the MAX11046 8-channel, 16-bit simultaneous-sampling ADC. It allows engineers to validate real-world performance-including INL (±2 LSB), SNR (92.3dB), and channel-to-channel T/H matching (100ps)-without designing custom PCBs. The MAX11046EVKIT+ includes all necessary bypassing, reference decoupling (RDC), and signal routing per Maxim's layout recommendations.

Does the MAX11046EVKIT+ support both TQFN and TQFP package variants of the MAX11046?

Yes, the MAX11046EVKIT+ is designed to accommodate both the 56-pin TQFN and 64-pin TQFP packages of the MAX11046. The board provides socketed or solder-down options with identical signal routing for AVDD, DGND, AGNDS, CH0–CH7, REFIO, and the full 16-bit parallel interface (DB0–DB15), preserving pin-compatible evaluation across package types.

Can the MAX11046EVKIT+ operate with an external reference instead of the internal 4.096V reference?

Yes, the MAX11046EVKIT+ supports external reference operation via the REFIO header. When an external 3.0V–4.25V reference is applied, the MAX11046EVKIT+ disables the internal reference buffer and routes the external source directly to the ADC core, enabling full-scale input ranges from ±4.0V to ±5.2V as specified in the MAX11046 datasheet.

What host interface options does the MAX11046EVKIT+ provide for data capture?

The MAX11046EVKIT+ exposes the native 20MHz parallel interface (DB0–DB15, RD, WR, CS, CONVST, EOC) via a 40-pin IDC header compatible with FPGA development platforms and microcontroller-based test rigs. It does not include USB or serial bridge ICs - data capture requires direct connection to a host with parallel bus capability and precise timing control for CONVST/EOC handshaking.

Is the MAX11046EVKIT+ RoHS-compliant and lead-free?

Yes, the MAX11046EVKIT+ uses RoHS-compliant components and lead-free PCB finish throughout. All included passive components, connectors, and the mounted MAX11046 device (in + suffix packaging) meet Maxim's lead(Pb)-free and RoHS directives, ensuring compliance for industrial and commercial deployment environments.
