- Highly integrated iSensor® intelligent sensors deliver shock and vibration detection to products where low power, low cost and small size are critical to system design.
The ADIS16240 is a fully integrated digital shock detection and capture system.

Norwood, MA (05/11/2009) - Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, is expanding its iSensor® intelligent sensor product family with the introduction of two highly-integrated inertial sensors that greatly simplify the complex task of embedded shock and vibration sensing within harsh industrial environments. Based on Analog Devices’ iMEMS® inertial sensor cores, these fully autonomous system-ready devices are one-tenth the cost and 100 times smaller than previous less-integrated, brick-level sensor modules. The programmable ADIS16240 impact sensor delivers superior power efficiency and user configurability in embedded applications while detecting and storing critical events for subsequent analysis. The programmable ADIS16220 digital vibration sensor provides designers with the capability to automatically capture profiles of subtle vibration shifts in machine performance and many other industrial applications that require wide-bandwidth sensing.

“Analog Devices’ new iSensor intelligent sensors enable designers to easily add high-performance shock and vibration sensing to a broader range of industrial and instrumentation applications at a fraction of the cost of previous monitors,” said Bob Scannell, business development manager, iSensor intelligent sensor products, Analog Devices. “By combining full programmability with performance, size, and power advantages, ADI’s ADIS16240 and ADIS16220 can be adapted easily into many different operating scenarios to sense, measure, process, and store signals for either offline or real-time analysis with more accuracy and energy efficiency than previously possible.”

ADIS16240 - Highly Accurate Impact Sensor Optimized for Low-Power Designs
The ADIS16240 is a fully integrated digital shock detection and capture system that combines ADI’s iMEMS technology with an embedded signal processing solution, enabling designers to cost-effectively convert critical motion data into valuable system information in low-power applications such as condition monitoring, impact detection, security sensing and tamper detection. The device’s low power triple-axis shock and impact sensor and recorder includes an integrated on-chip programmable event capture buffer, which monitors for user programmed shock thresholds and holds pre- and post-event data, time-stamp, temperature and voltage.

Programming features and data access are controlled from a standard SPI (serial peripheral interface) port, making the ADIS16240 compatible with many existing systems. Once implemented in the system, the device operates autonomously, capturing multiple events for later analysis or providing real-time indication of excessive shock environments.

The ADIS16240 consumes less than 1 milliamp in continuous sampling mode, making it ideal for use in portable or battery-powered security devices, remote safety monitors or products that monitor the condition of goods or shipments. With a usable bandwidth of up to 1.6 kHz, the ADIS16240 is significantly more capable of capturing critical shock events than previously available solutions.

ADIS16220 - Programmable Wide-Bandwidth Sensor Simplifies Access to Information
The ADIS16220 is a digital vibration monitor that combines ADI’s award winning and industry-leading wide-bandwidth iMEMS sensing technology with an embedded signal processor and data capture system. A digital interface combined with a unique 22-kHz wide-bandwidth, high-g accelerometer provides engineers—with or without MEMS design expertise—with the ability to design embedded vibration monitoring capabilities into industrial systems through a convenient user interface, optimized power dissipation and user configurable controls.

The fully integrated and programmable vibration sensor with an SPI interface captures 1024 samples on each of three inputs, at 100 kSPS (kilosamples per second). Programmable software features, which include peak sample and hold, trigger source and threshold levels, internal filtering and power management make the device easy to tune to specific applications or operational scenarios, reducing time-to-market and maintenance costs.

The 22-kHz sensor bandwidth, ±70-g dynamic range, and 100-kHz sample rate make the ADIS16220 effective for industrial applications, including safety controls, embedded vibration monitoring and bearing condition monitoring. The internal high-rate-capture buffers allow complete event profile capture and ease the task of remote data transmission. Data capture is configurable to be user-initiated, timer initiated, or event initiated, allowing complete flexibility to meet either minimum power requirements or real-time notification of system problems.
