AD4030-24-KTZ EVAL-AD4030-24 24-Bit 2 MSPS SAR ADC Kit | ADI

The Analog Devices EVAL-AD4030-24-KTZ is an evaluation board for the AD4030-24, a 24-bit precision successive approximation register (SAR) analog-to-digital converter that supports throughput up to 2 MSPS, assembled on a configurable analog front-end (AFE) demonstration platform. The kit provides a full demonstration of the AD4030-24's Easy Drive input structure, integrated reference buffer, and zero-latency track-and-hold, enabling engineers to characterize the converter's ±0.9 ppm maximum INL, 24-bit no-missing-codes performance, and 109 dB dynamic range when paired with a 5 V reference. A SAR ADC is a Nyquist-rate converter that uses a binary-search algorithm against a precision DAC to resolve each analog sample in N successive clock cycles, where N is the output resolution. Within the broader data-converter taxonomy, the SAR family sits between high-speed flash and pipeline converters on one side and ultra-high-resolution delta-sigma converters on the other; SAR parts dominate when designers need 16-24 bit resolution with deterministic, zero-latency response and multi-MHz sample rates. The AD4030-24 occupies the high-precision end of this family. Key features of the underlying AD4030-24 silicon include ±0.9 ppm maximum integral nonlinearity (INL), guaranteed no missing codes at 24 bits across the full -40 C to +125 C operating range, a 2 MSPS sample rate in turbo mode (500 kSPS for the lower-power AD4032-24), an Easy Drive analog input that greatly reduces input current transients, and an integrated reference buffer with on-chip decoupling that minimizes external BOM. The 7 mm x 7 mm 64-ball CSP_BGA silicon package routes all critical reference and supply bypass internally. Architecturally, the converter combines a precision CDAC, a high-bandwidth input track-and-hold, and a low-noise reference buffer. Easy Drive simplifies system design by absorbing the kickback current that normally flows when a SAR ADC samples a low-bandwidth source, allowing high-impedance or unbuffered sensors to connect directly to the input pins without degrading distortion performance. Typical applications for the EVAL-AD4030-24-KTZ platform include precision instrumentation front-ends (weigh scales, industrial process controls), data-acquisition modules for seismic and vibration analysis, medical diagnostic instrumentation, and seismic/energy-exploration receivers. The board is also widely used as a benchmark when evaluating next-generation 24-bit precision SAR alternatives such as the TI ADS127L11. Design tip: when characterizing the AD4030-24, supply a clean 5 V external reference for best dynamic range and use the board's on-board LDO for AVDD rather than sharing a noisy switching rail; this preserves the converter's 109 dB dynamic range in real measurements.
