GENERAL DESCRIPTION

The ADcmXL1021-1 is a complete vibration sensing system that

combines high performance vibration sensing (using a micro-

electromechanical systems (MEMS) accelerometer) with a variety

of signal processing functions to simplify the development of

smart sensor nodes in condition-based monitoring (CBM)

systems. The typical ultralow noise density (26 μg/√Hz) in the

MEMS accelerometers supports excellent resolution. The wide

bandwidth (dc to 10 kHz within 3 dB flatness) enables tracking

of key vibration signatures on many machine platforms.

Real-time data streaming at 220 kSPS

Burst mode communication with CRC-16 error checking

Storage: 10 data records

On demand self test with status flags

The signal processing includes high speed data sampling

(220 kSPS), 4096 time sample record lengths, filtering,

windowing, fast Fourier transform (FFT), user configurable

spectral or time statistic alarms, and error flags. The serial

peripheral interface (SPI) provides access to a register structure

that contains the vibration data and a wide range of user

configurable functions.

Sleep mode with external and timer driven wakeup

Digital temperature and power supply measurements

SPI-compatible serial interface

Identification registers: factory preprogrammed serial

number, device ID, user programmable ID

Single-supply operation: 3.0 V to 3.6 V

Operating temperature range: −40°C to +10±°C

Automatic shutdown at 12±°C (junction temperature)

23.7 mm × 27.0 mm × 12.4 mm aluminum package

36 mm flexible, 14-lead module with integrated flexible

connector

The ADcmXL1021-1 is available in a 23.7 mm × 27.0 mm ×

12.4 mm aluminum package with four mounting flanges to

support installation with standard machine screws. This light

weight package (13 g) provides consistent mechanical coupling

to the core sensors over a broad frequency range. The electrical

interface is through a 14-lead connector on a 36 mm flexible

cable, which enables a wide range of location and orientation

options for system mating connectors.

Mass: 13 g

APPLICATIONS

Vibration analysis

Condition-based monitoring (CbM) systems

Machine health

The ADcmXL1021-1 requires only a single, 3.3 V power supply

and supports an operating temperature range of −40°C to +105°C.

Instrumentation and diagnostics

Safety shutoff sensing

Multifunction pin names may be referenced by their relevant

function only.
