SCA1000-D01

The SCA1000-D01 is a 2-axis Accelerometer consisting of two silicon bulk micro machined sensing element chips and a signal conditioning ASIC. The chips are mounted on a pre-moulded package and wire bonded to appropriate contacts. The sensing elements and ASIC are protected with silicone gel and lid. Enhanced failure detection feature of the device are - true self test by deflecting the sensing elements' proof mass by electrostatic force. Deflection voltage is adjustable with two memory bits for both channels. The self-test is channel specific and separately activated for both channels by digital on-off commands via dedicated pins or via SPI bus. Continuous sensing element interconnection failure check is another enhanced failure detection feature of the device.

• Two ratiometric analogue outputs in relation to supply voltage
• Wide load driving capability
• Serial Peripheral Interface (SPI) provides digital output for both channels
• Factory programmable filter settings
• Offset and sensitivity calibration
• Linear temperature compensation
• Non-volatile programming
