FEATURES Dual axis accelerometer fabricated on a single CMOS IC Monolithic design with mixed mode signal processing Zero-g temperature stability better than ± 300 mg from - 40C to 125C Sensitivity temperature pensation better that ± 10% from -40C to 125C +/- 13.3g dynamic range, 150m V/g sensitivity 29Hz bandwidth On Demand Self Test >50,000 g shock survival rating 4.75V to 5.25V single supply operation Small surface mount package, 5.5mm x 5.5mm x 2.7mm XZ mounting Ro HS pliant AEC-Q100 class 1 AUTOMOTIVE APPLICATIONS - Active Suspension Control - Roll Over Detection GENERAL DESCRIPTION The MXR7150VW is a low cost, dual axis accelerometer built on a standard, submicron CMOS process. It measures acceleration with a full-scale range of -13.3g to +13.3g and a sensitivity of 150m V/g. The MXR7150VW provides a g-proportional rationmetric analog output above/ below the zero-g point at 50% of the supply voltage. The typical noise floor is 8 mg. The inherent 3d B roll off of the device is 29Hz providing immunity to and attenuation of higher frequency vibrations present in automotive applications. The MXR7150VW is packaged in a hermetically sealed LCC surface mount package (5.5 mm x 5.5 mm x 2.7 mm height), and the package can be used for XZ sensing, its operation temperature is -40C to +125C. It can measure both dynamic acceleration (e.g., vibration) and static acceleration (e.g., gravity).
