Combined Gyroscope

and Dual-Axis Accelerometer

Data Sheet

ADXC1500

FEATURES

GENERAL DESCRIPTION

Combined gyroscope and dual-axis, low g accelerometer

Temperature compensated, high precision bias, and

sensitivity performance

The ADXC1500 is a yaw rate gyroscope and dual-axis

accelerometer combined in a single package. It is designed for

electronic stability control (ESC) and other high performance

applications that require yaw rate and acceleration signals simultan-

eously. An internal temperature sensor compensates offset and

sensitivity performance, providing excellent stability over the

−40°C to +105°C temperature range.

30 mg accelerometer bias stability over temperature

2°/sec gyroscope null stability over temperature

2.5 mg rms typical accelerometer noise at 35.6 Hz

0.1°/sec rms typical gyroscope noise at 35.6 Hz

Gyroscope: linear acceleration rejection of 0.03°/sec/g

Acceleration: 32 g overload performance

SPI digital output with a 16-bit data-word and a 4-bit CRC

Comprehensive electromechanical fail-safe features

6 kHz data update rate

Programmable filter response

<16 mA quiescent current draw

3.3 V or 5 V operation

−40°C to +105°C temperature range

A digital serial port interface (SPI) transmits the yaw rate and

acceleration data to a host microcontroller. A 4-bit cyclical

redundancy check (CRC) provides fault coverage for the

transmitted SPI data, and internal fault detection routines

ensure the integrity of all reported yaw rates and acceleration

data. A fully integrated electromechanical continuous self test

(CST) routine provides run-time diagnostic capability for

assessing the health of each MEMS element.

An advanced gyroscope sensor design rejects the linear accel-

eration effects of shock and vibration, enabling the ADXC1500

to operate in harsh environments. The accelerometer signal

chain is designed to prevent overload conditions from

occurring in these same harsh environments.

16-lead inverted cavity SOIC package for robust EMI

performance

Qualified for automotive applications

APPLICATIONS

Electronic stability control

Chassis control

The ADXC1500 is designed to operate at either 3.3 V or 5 V. At

less than 16 mA current consumption, the ADXC1500 can be

used in energy sensitive applications.
