Key features

- Customer programmable g-ranges (1g, 1.5g, 2g, 3g, 4g, 8g, 16g)

- Customer programmable integrated digital filters (no external components):

- 8 low-pass filters: 10, 20, 40, 75, 150, 300, 600, 1200Hz

- 1 high-pass-filter: 1Hz

- 1 band-pass-filter: 0.2 . . . 300Hz

- Customer programmable interrupt features:

- wake-up (power management)

- low-g detection (free-fall)

- high-g-detection

- tap-sensing functionality

- slope detection (any motion)

- Customer programmable power modes:

- 4 standard modes: low noise, low power, super-low noise, ultra-low noise

- sleep mode

- wake-up mode

- Customer calibration possibility for:

- Offset

- Sensitivity

- Temperature coefficient of offset (TCO)

- Temperature coefficient of sensitivity (TCS)

- Enhanced features (customer programmable)

- Switch for by-passing internal band-gap -> very low voltage operation with full

performance (by using a high-performance external band-gap)

- Sample skipping (reduction of µC load by reduction of new-data interrupts)

- 14 or 12 bit ADC-conversion (switch-able) for read-out acceleration

- New-data interrupt to provide “synch-signal” to microcontroller (reduction of

noise by decreasing traffic noise in case of I²C or SPI-traffic)

- 2 selectable I²C addresses

- Offset regulation (each channel) with subsequent interrupt generation

- Course regulation (accuracy typically better than ±30 LSB)

- fine regulation (accuracy typically ±4 LSB at low bandwidths)

- in-field re-calibration possibility after regulation

- Full self-test capability

- logic only

- full sensor signal path (including or excluding damping measurement)
