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
