GENERAL DESCRIPTION

The ADIS16204 is a programmable impact sensor in a single

compact package enabled by the Analog Devices iSensor™

integration. By enhancing the Analog Devices iMEMS® sensor

technology with an embedded signal processing solution, the

ADIS16204 provides tunable digital sensor data in a convenient

format that can be accessed using a serial peripheral interface

(SPI). The SPI interface provides access to measurements for

dual-axis linear acceleration, a root-sum-square (RSS) of both

axes, temperature, power supply, and one auxiliary analog

input. Easy access to digital sensor data provides developers

with a system-ready device, reducing development time, cost,

and program risk.

Unique characteristics of the end system are accommodated

easily through several built-in features, such as a single

command in-system offset calibration, along with convenient

sample rate control.

The ADIS16204 offers the following embedded features, which

eliminate the need for external circuitry and provide a simplified

system interface:

•

The ADIS16204 offers two power management features for

managing system-level power dissipation: low power mode and

a configurable shutdown feature.

The ADIS16204 is available in a 9.2 mm × 9.2 mm × 3.9 mm

laminate-based land grid array (LGA) package with a

temperature range of −40°C to +105°C.
