Product details
Overview
ADIS16240ABCZ from Analog Devices is a fully integrated digital triple-axis shock detection and recording system with ±19 g dynamic range, 1600 Hz (X/Y) and 550 Hz (Z) sensor bandwidth, 100 µA sleep current, nonvolatile flash event storage, and real-time clock. It autonomously captures impact events in logistics monitoring, safety shut-off systems, and tamper-detection applications.
For engineers reviewing the ADIS16240ABCZ datasheet, ADIS16240ABCZ pinout, ADIS16240ABCZ application, or ADIS16240ABCZ equivalent, this page delivers verified technical context, SPI interface timing constraints, peak XYZ sum-of-squares output capability, programmable dual analog comparator triggers, and flash endurance (10,000 cycles) for long-term field deployment.
Technical Context
The ADIS16240ABCZ implements a MEMS-based triple-axis accelerometer with digitally controlled sample rate up to 4096 SPS, internal/external trigger modes, and autonomous event capture into a 3 × 8192-sample buffer backed by nonvolatile flash memory. Its SPI interface operates in Mode 3 (CPOL = 1, CPHA = 1) at ≤2.5 MHz with full-duplex 16-bit transfers.
Signal processing includes peak acceleration sample-and-hold per axis, real-time XYZ sum-of-squares calculation (12-bit output), programmable alarm thresholds on six data sources (X/Y/Z accel, temp, supply, AUX ADC), and self-test activation via ST pin. Power management supports wake-up scheduling, sleep mode, and configurable sampling periods.

Equivalent & Alternatives
The following parts are listed as comparable options for similar shock detection and recording applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADIS16203AMLZ | Lacks real-time clock, flash storage, and programmable alarms; only provides continuous streaming output | Suitable for real-time vibration analysis but not autonomous event logging | Select when continuous data streaming to host is preferred over local flash-based event capture |
| ADXL372BCCZ | Higher bandwidth (3200 Hz), lower power (22 µA sleep), but no flash memory or RTC; uses I²C/SPI | Better for ultra-low-power wake-on-shock in wearable or IoT edge nodes without timestamped storage | Select when minimizing sleep current is critical and external host handles event storage and timekeeping |
Compared with ADIS16240ABCZ, ADIS16203AMLZ omits nonvolatile event storage and scheduling, while ADXL372BCCZ trades flash and RTC for lower sleep current and higher bandwidth-making ADIS16240ABCZ uniquely suited for standalone, timestamped impact forensics in unattended deployments.

FAQ
What is the maximum sample rate supported by the ADIS16240ABCZ?
The ADIS16240ABCZ supports a maximum digitized sample rate of 4096 SPS, configurable via the SMPL_PRD register. This rate applies to continuous sampling mode and enables high-fidelity capture of fast transients such as impacts or drops. At full rate, average supply current rises to 1 mA (VDD = 2.5 V), with instantaneous peaks reaching 30 mA during conversion cycles.
Does the ADIS16240ABCZ include nonvolatile memory for event storage?
Yes, the ADIS16240ABCZ integrates nonvolatile flash memory capable of storing up to 3 × 8192 samples (X/Y/Z axes) per triggered event, with 10,000 write cycles endurance and 20-year data retention at 85°C junction temperature. Each stored event includes temperature, supply voltage, and real-time clock timestamps automatically captured in the event header.
How does the ADIS16240ABCZ handle external trigger inputs?
The ADIS16240ABCZ accepts external triggers via two dedicated analog comparator inputs (CMP1 and CMP2), each configurable with independent voltage thresholds. When an input crosses its threshold, it initiates event capture with user-defined pre-trigger buffer depth. These inputs are 5 V tolerant and support direct connection to external sensors or switch closures without level-shifting circuitry.
What is the function of the XA, YA, and ZA pins on the ADIS16240ABCZ?
The XA, YA, and ZA pins on the ADIS16240ABCZ provide buffered analog low-pass filtered outputs of the respective accelerometer axes. These outputs enable external oscilloscope monitoring, analog signal conditioning, or secondary diagnostic verification independent of the digital SPI path. They are not required for normal digital operation but support debug, calibration, and redundancy use cases.
Can the ADIS16240ABCZ operate from a 2.4 V supply?
Yes, the ADIS16240ABCZ supports single-supply operation from 2.4 V to 3.6 V. At 2.4 V, it maintains full functionality including ±19 g dynamic range, 100 µA sleep current, and SPI communication compliance. Supply current vs. voltage testing confirms stable operation across this range, with typical average current of 1 mA at 2.5 V and 4096 SPS sampling.
