GENERAL DESCRIPTION
The ADIS16201 is a complete, dual-axis acceleration and
inclination angle measurement system available 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
ADIS16201 provides factory calibrated and 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, dual-
axis linear inclination angle, temperature, power supply, and
one auxiliary analog input. Easy access to calibrated 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 and bandwidth control.
The ADIS16201 offers the following embedded features, which
eliminate the need for external circuitry and provide a simplified
system interface:
• Configurable alarm function
• Auxiliary 12-bit ADC
• Auxiliary 12-bit DAC
• Configurable digital I/O port
• Digital self-test function
The ADIS16201 offers two power management features for
managing system-level power dissipation: low power mode and
a configurable shutdown feature.
The ADIS16201 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 +125°C.
