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:
Peak sample and hold
Programmable Event Recording
Configurable trigger levels
Auxiliary 12-bit ADC and DAC
Configurable digital I/O port
Digital self-test function
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.
