Analog Devices Inc. EVAL-AD4030-24-KTZ

Overview

EVAL-AD4030-24-KTZ from Analog Devices is an evaluation board for the AD4030-24 24-bit, 2 MSPS SAR ADC, enabling rapid prototyping of high-precision data acquisition systems in automatic test equipment and scientific instrumentation. It supports Flexi-SPI interface configurations (1–4 SDO lanes), echo clock mode for digital isolator integration, and programmable block averaging up to 2¹⁶ decimation.

For engineers reviewing the EVAL-AD4030-24-KTZ datasheet, EVAL-AD4030-24-KTZ pinout, EVAL-AD4030-24-KTZ application, or EVAL-AD4030-24-KTZ equivalent, this board provides full access to the AD4030-24's Easy Drive™ analog inputs, integrated reference buffer with 2 µF bypass, ±0.9 ppm INL over −40°C to +125°C, and 108.4 dB SNR - critical for validating signal chain performance before production design.

Technical Context

The EVAL-AD4030-24-KTZ implements a complete hardware platform for evaluating the AD4030-24's differential and single-ended input operation, including precision analog front-end conditioning, configurable power supply sequencing (VDD_5V, VDD_1.8V, VIO), and flexible SPI timing modes (SDR/DDR, host clock, echo clock). It exposes all 64-ball CSP_BGA pins via edge-mounted connectors and solder jumpers for REFIN/REF selection, CNV timing control, and SDO lane configuration.

It supports the AD4030-24's key digital features: programmable averaging filter (2–65536×), overrange/synchronization bit output, 1.2 µA low input current at 2 MSPS, and wide common-mode range (−1/128 × VREF to +129/128 × VREF). The board includes on-board 4.096 V and 5 V reference options, low-noise LDOs, and layout-optimized ground planes to preserve 109 dB dynamic range and −169 dBFS/Hz NSD.

FAQ

What is the primary function of the EVAL-AD4030-24-KTZ?

The EVAL-AD4030-24-KTZ is an evaluation board purpose-built to characterize and validate the AD4030-24 24-bit, 2 MSPS SAR ADC under real-world conditions. It provides full access to all analog inputs, digital interfaces (Flexi-SPI), reference options (REFIN/REF), and power domains, enabling engineers to verify INL (±0.9 ppm), SNR (108.4 dB), and timing behavior before integrating the AD4030-24 into final designs.

Does the EVAL-AD4030-24-KTZ support both AD4030-24 and AD4032-24 devices?

No - the EVAL-AD4030-24-KTZ is optimized specifically for the AD4030-24 (2 MSPS variant). While the AD4032-24 shares the same 64-ball CSP_BGA package and pinout, its lower 500 kSPS throughput and different acquisition timing require distinct layout considerations. Analog Devices provides separate evaluation hardware (e.g., EVAL-AD4032-24-KTZ) for that variant.

How does the EVAL-AD4030-24-KTZ implement Easy Drive™ functionality verification?

The EVAL-AD4030-24-KTZ includes low-impedance, matched analog input paths with selectable termination and precharge buffers, allowing direct measurement of the AD4030-24's 1.2 µA input current at 2 MSPS and wide common-mode range (−1/128 × VREF to +129/128 × VREF). This enables validation of reduced front-end amplifier burden and simplified signal conditioning - core benefits of Easy Drive™.

Can the EVAL-AD4030-24-KTZ be used with digital isolators?

Yes - the EVAL-AD4030-24-KTZ supports echo clock mode, where the BUSY_SCKOUT pin outputs a synchronized copy of the host SCK signal. This eliminates setup/hold timing violations across isolation barriers and is explicitly validated in the AD4030-24 datasheet. The board provides isolated power and signal routing headers compatible with standard digital isolators (e.g., ADuM series).

What reference voltage options are available on the EVAL-AD4030-24-KTZ?

The EVAL-AD4030-24-KTZ supports both buffered (via REFIN) and unbuffered (via REF) reference configurations. On-board options include a precision 4.096 V reference and a 5 V LDO, aligning with the AD4030-24's specified REFIN range (4.096 V–5 V) and internal reference buffer specifications (±25 µV offset, ±0.3 µV/°C drift).
