Basic Description

The BMA530 is an advanced,ultra-small, triaxial low-g accelerometer with digital interfaces. The sensor is suitable for

low-power and demanding consumer electronics applications. The BMA530 integrates

a 16 bit digital, triaxial accelerometer with range configurable to 2 g, 4 g, 8 g, 16 g

a 8 bit digital temperature sensor for an operating temperature range –40 C ... 85 C
