Analog Devices Inc./Maxim Integrated MAX14001EVSYS#

Overview

MAX14001EVSYS# from Maxim Integrated is an evaluation system designed to accelerate development and validation of the MAX14001 isolated single-channel analog-to-digital converter with programmable voltage comparators and inrush current control for configurable binary input modules. It includes the MAX14001EVKIT# hardware platform and USB2PMB2 adapter board, supports 300VDC nominal input monitoring via full-wave rectification (U1), delivers SPI communication up to 5MHz, and enables dual-channel, daisy-chain, or single-channel test configurations.

For engineers reviewing the MAX14001EVSYS# datasheet, MAX14001EVSYS# pinout, MAX14001EVSYS# application, or MAX14001EVSYS# equivalent, this EV system provides a fully assembled, RoHS-compliant platform with GUI-driven configuration of ADC full-scale voltage (13.75V max), comparator thresholds, inrush timing, fault reporting, and reference selection - all without requiring custom PCB design or low-level register programming.

Technical Context

The MAX14001EVSYS# implements two independent MAX14001AAP+ devices (U1 and U2) on a single board, each featuring galvanically isolated 16-bit sigma-delta ADCs, programmable voltage comparators, and depletion-mode FET gate drivers for inrush current control. The system supports three distinct SPI interface modes - single channel (PMOD1 or PMOD2), daisy-chain (U1 DOUT → U2 DIN), and dual channel (CS1/CS2 multiplexed over PMOD1) - configured via physical jumpers per Table 2.

Hardware flexibility includes selectable input conditioning: U1 supports full-wave rectified 300VDC input with MELF resistor divider (R1–R4), while U2 supports half-wave rectified input (T2); both offer internal 1.25V reference or external shunt/series 1.25V references (e.g., MAX6006 or REF3312), with jumper-configurable bias paths, gate drive outputs, and FAULT/COUT signal routing to Pmod-compatible headers.

FAQ

What does the MAX14001EVSYS# include?

The MAX14001EVSYS# includes the MAX14001EVKIT# evaluation board populated with two MAX14001AAP+ ICs (U1 and U2), the USB2PMB2 adapter board, and a micro-USB cable. It does not include standoffs, screws, or external DC supplies. All components are fully assembled and tested per Maxim Integrated's production standards.

Can the MAX14001EVSYS# evaluate both MAX14001 and MAX14002 devices?

No - the MAX14001EVSYS# is specifically configured for the MAX14001AAP+. While the hardware layout is shared with the MAX14002EVSYS#, the MAX14001EVSYS# ships with MAX14001AAP+ devices installed (U1 and U2). Evaluation of MAX14002 requires the MAX14002EVSYS# or separate MAX14002EVKIT#.

Does the MAX14001EVSYS# support high-voltage input testing out of the box?

The MAX14001EVSYS# supports high-voltage operation but requires jumper reconfiguration: J4 and J13 must be closed for full-wave rectification and 300VDC input on U1 (T1 terminal block), and safety-rated X/Y capacitors (C9, C22, etc.) must be manually installed. Default jumper settings configure safe 13.75VDC simulation mode.

How is SPI communication implemented on the MAX14001EVSYS#?

SPI communication on the MAX14001EVSYS# is routed through Pmod-compatible 12-pin headers (PMOD1 and PMOD2), interfacing with the USB2PMB2 adapter board. The system supports 5MHz clock rate and three modes: single channel (one device), daisy-chain (U1 DOUT → U2 DIN), or dual channel (independent CS1/CS2), all selected via physical jumpers - no firmware changes needed.

Is Windows driver installation required for the MAX14001EVSYS#?

Yes - the MAX14001EVSYS# requires FTDI Chip CDM drivers installed via the MAX1400XEVKitSetupV1.0.exe installer. This package also deploys the GUI software, configures COM port enumeration, and enables communication between the PC and the USB2PMB2 adapter. Driver installation is mandatory before launching the EV kit software.
