MMA81XXEG/MMA82XXEG/MMA82XXTEG family is a satellite accelerometer which is comprised of a single axis, variable ca-pacitance sensing element with a single channel interface IC. The interface IC converts the analog signal to a digital format whichis transmitted in accordance with the DSI-2.0 specification.1.1
MMA81XXEG/MMA82XXEG/MMA82XXTEG family is a satellite accelerometer which is comprised of a single axis, variable ca-pacitance sensing element with a single channel interface IC. The interface IC converts the analog signal to a digital format whichis transmitted in accordance with the DSI-2.0 specification.1.1OVERVIEWSignal conditioning begins with a Capacitance to Voltage conversion (C to V) followed by a 2-stage switched capacitor amplifier.This amplifier has adjustable offset and gain trimming and is followed by a low-pass switched capacitor filter with Bessel function.Offset and gain of the interface IC are trimmed during the manufacturing process. Following the filter the signal passes to theoutput stage. The output stage sensitivity incorporates temperature compensation.The output of the accelerometer signal conditioning is converted to a digital signal by an A/D converter. After this conversion theresultant digital word is converted to a serial data stream which may be transmitted via the DSI bus. Power for the device isderived from voltage applied to the BUSIN/BUSOUT and VSS pins. Bus voltage is rectified and applied to an external capacitorconnected to the HCAP pin. During data transmissions, the device operates from stored charge on the external capacitor. Anintegrated regulator supplies fixed voltage to internal circuitry.A self-test voltage may be applied to the electrostatic deflection plate in the sensing element. Self-Test voltage is factory trimmed.Other support circuits include a bandgap voltage reference for the bias sources and the self-test voltage.A total of 128 bits of One-Time Programmable (OTP) memory, are provided for storage of factory trim data, serial number anddevice characteristics. Eighty OTP bits are available for customer programming. These eighty OTP bits may be programmed viathe DSI Bus or through the serial test/trim interface. OTP integrity is verified through continuous parity checking. Separate paritybits are provided for factory and customer programmed data. In the event that a parity fault is detected, the reserved value ofzero is transmitted in response to a Read Acceleration Data command.A block diagram illustrating the major elements of the device is shown in Figure 1-1.ORDERING INFORMATIONDevice NameX-axis g-LevelZ-axis g-LevelTemperature RangeSOIC 16 PackagePackagingMMA8225EGR2250—-40 to +125°C475-01Tape & ReelMMA8225EG250—-40 to +125°C475-01TubesMMA8215EGR2150—-40 to +125°C475-01Tape & ReelMMA8215EG150—-40 to +125°C475-01TubesMMA8210TEGR2100—-40 to +125°C475-01Tape & ReelMMA8210TEG100—-40 to +125°C475-01TubesMMA8205TEGR250—-40 to +125°C475-01Tape & ReelMMA8205TEG50—-40 to +125°C475-01TubesMMA8204EGR240—-40 to +125°C475-01Tape & ReelMMA8204EG40—-40 to +125°C475-01TubesMMA8202EGR220—-40 to +125°C475-01Tape & ReelMMA8202EG20—-40 to +125°C475-01TubesMMA8125EGR2—250-40 to +125°C475-01Tape & ReelMMA8125EG—250-40 to +125°C475-01TubesMMA8115EGR2—150-40 to +125°C475-01Tape & ReelMMA8115EG—150-40 to +125°C475-01TubesMMA8110EGR2—100-40 to +125°C475-01Tape & ReelMMA8110EG—100-40 to +125°C475-01TubesMMA8104EGR2—40-40 to +125°C475-01Tape & ReelMMA8104EG—40-40 to +125°C475-01Tubes
