Analog Devices Inc. EV-ADUCM350DISZ

Overview

EV-ADUCM350DISZ from Analog Devices is a fully integrated, coin-cell-powered evaluation platform for the ADuCM350 precision analog front-end microcontroller. It enables high-accuracy amperometric, voltametric, and impedometric measurements with its 16-bit, 160 kSPS ADC; 12-bit DAC; ultralow-leakage switch matrix; and embedded DFT-based impedance engine - all operating within −40°C to +85°C temperature range and housed in an 8 mm × 8 mm CSP_BGA package.

For engineers reviewing the EV-ADUCM350DISZ datasheet, EV-ADUCM350DISZ pinout, EV-ADUCM350DISZ application, or EV-ADUCM350DISZ equivalent, this board supports rapid validation of biosensor interfaces, body-worn diagnostic signal chains, and low-power electrochemical measurement systems requiring calibrated voltage/current excitation, real-time impedance analysis, and USB-hosted data streaming.

Technical Context

The EV-ADUCM350DISZ implements the full ADuCM350 reference design, including its dual-LDO power architecture (HP/LP LDOs), AFE-to-Cortex-M3 AHB/DMA interface, and configurable excitation/measurement signal paths. It integrates the on-chip 32.768 kHz crystal oscillator, 16 MHz HF oscillator, and PLLs for system clock generation, enabling precise timing control for DFT-based impedance sweeps and synchronized ADC sampling.

Hardware-level support includes direct connection to the ADuCM350's 120-ball CSP_BGA via a socketed carrier board, provisioned test points for all AFE channels (4 voltage, 8 current), dedicated RCAL/RTIA networks, and USB 2.0 full-speed interface routed to an onboard micro-B connector - all configured per UG-587 hardware reference manual layout guidelines.

FAQ

What is the primary purpose of the EV-ADUCM350DISZ?

The EV-ADUCM350DISZ is an official Analog Devices evaluation board intended for hardware and firmware validation of the ADuCM350 meter-on-a-chip. It provides complete access to all AFE channels, USB connectivity, debug interfaces, and calibrated reference components - enabling engineers to verify sensor interface performance, impedance measurement accuracy, and low-power operation without custom PCB design. The EV-ADUCM350DISZ directly supports development of clinical-grade portable diagnostics using the ADuCM350.

Does the EV-ADUCM350DISZ include the ADuCM350 IC pre-mounted?

Yes, the EV-ADUCM350DISZ ships with the ADuCM350 IC (120-ball CSP_BGA package) securely mounted on a socketed carrier board. This allows for reliable electrical connection while preserving the ability to replace or upgrade the device if needed. All critical AFE signals - including voltage inputs, current sinks/sources, DAC outputs, and reference nodes - are brought out to test points or headers as specified in UG-587.

Can the EV-ADUCM350DISZ be used for production deployment?

No, the EV-ADUCM350DISZ is strictly an evaluation and development tool, not a production-ready module. It lacks conformal coating, industrial-grade mechanical retention, ESD-hardened enclosure, or regulatory certifications required for end-product integration. For volume deployment, designers must implement the ADuCM350 in their own PCB layout following the ADuCM350 datasheet and UG-587 layout guidelines - using the EV-ADUCM350DISZ solely for functional verification and algorithm development.

What software tools are supported for the EV-ADUCM350DISZ?

The EV-ADUCM350DISZ is fully supported by Analog Devices' CrossCore Embedded Studio IDE, including device-specific BSPs, example projects for impedance spectroscopy, voltammetry, and CapTouch, and drivers compliant with the ADuCM350 HAL. Firmware can be flashed via SWD/JTAG using the onboard debug header, and real-time data streaming is enabled through the integrated USB CDC virtual COM port - allowing immediate visualization of sensor output in Python, MATLAB, or custom host applications.

Is external crystal required for basic operation of the EV-ADUCM350DISZ?

No - the EV-ADUCM350DISZ includes both the 32.768 kHz low-frequency crystal (for RTC and wake-up timers) and the 16 MHz high-frequency crystal (for system clock and PLL reference) pre-soldered and connected per ADuCM350 requirements. These crystals are essential for achieving the specified timing accuracy in DFT-based impedance measurements and USB communication; no external oscillator components need to be added for default operation.
