O _{GENERAL DESCRIPTION}
The ADIS16204 is a fully-contained programmable impact
sensor in a single compact package enabled by the Analog
S Devices, Inc. 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
B _{a serial peripheral interface (SPI). The SPI provides access to}
measurements for dual-axis linear acceleration, a root sum
square (RSS) of both axes, temperature, power supply, an
O ^{auxiliary analog input, and an event capture buffer memory. Easy}

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 (dual, 1K × 16 bit)
 RSS output (total shock in the XY plane)
 Configurable alarms
 Auxiliary 12-bit ADC and DAC
 Configurable digital I/O port
access to digital sensor data provides users with a system-ready
device, reducing development time, cost, and program risk.
 Digital self-test function
Unique characteristics of the end system are accommodated
easily through several built-in features, such as a single command
in-system bias null/offset calibration, along with convenient
The ADIS16204 offers two power management features for
managing system-level power dissipation: low power mode
and a configurable shutdown feature.
sample rate control.
The ADIS16204 is available in a 9.2 mm × 9.2 mm × 3.9 mm
laminate-based land grid array (LGA) package with a tem-
perature range of −40°C to +105°C.
