ISM303DAC
High-performance, low-power, compact
3D accelerometer and 3D magnetometer module
Datasheet - production data
Description
The ISM303DAC is a high-performance, low-
power system-in-package featuring a 3D digital
linear acceleration sensor and a 3D digital
magnetic sensor.
The ISM303DAC has user-selectable linear
acceleration full scales of ±2g/±4g/±8g/16 g and

is capable of measuring accelerations with output
data rates from 1 Hz to 6400 Hz. The device has
a magnetic field dynamic range of up to

150 Hz. The ISM303DAC includes an I C serial
channels
bus interface that supports standard, fast mode,
fast mode plus, and high-speed (100 kHz,
400 kHz, 1 MHz, and 3.4 MHz) and an SPI serial
standard interface.
Up to ±50 gauss magnetic dynamic range
±2/±4/±8/16 g selectable acceleration full
scales
The ISM303DAC has an integrated 256-level first-
in, first-out (FIFO) buffer for the accelerometer
data which can be used to limit the intervention of
the host processor.

SPI / I C serial interfaces
The embedded self-test capability allows the user
to check the functioning of the sensor in the final
application.
Analog supply voltage 1.71 V to 1.98 V
Programmable interrupt generators for free-
fall, motion and magnetic field detection
The system can be configured to generate an
interrupt signal for free-fall, motion detection and
magnetic field detection. The magnetic and
accelerometer blocks can be enabled or put into
power-down mode separately.
Embedded self-test both for the accelerometer
and magnetometer
Embedded 256-level FIFO
Embedded temperature sensor
