Model 1210

      The Model 1210 is a inexpensive,integrated accelerometer and can be used in zero to medium frequency instrumentation applications. Each miniature, hermetically sealed package combines a micro-machined capacitive sense element and a custom integrated circuit that includes a sense amplifier and differential output stage. It is relatively insensitive to temperature changes and gradients. Each device is marked with a serial number on its bottom surface for traceability. An optional calibration test sheet (1210-TST) is also available which lists the measured bias, scale factor,linearity, operating current and frequency response.
      The Model 1210 has ten features:(1)±4V Differential Output or 0.5V to 4.5V Single Ended Output.(2)Fully Calibrated.(3)Responds to DC & AC Acceleration.(4)-55 to +125 Operation.(5)+5 VDC, 7 mA Power(typical).(6)Non-Standard g Ranges Available.(7)Integrated Sensor & Amplifier.(8)LCC or J-Lead Surface Mount Package.(9)Serialized for Traceability.(10)RoHS Compliant.
      The Model 1210 produces two analog output voltages which vary with acceleration as shown in the figure below. The outputs can be used either in differential or single ended mode referenced to +2.5 volts. Two reference voltages, +5.0 and +2.5 volts (nominal), are required; the output scale factor is ratiometric to the +5 volt reference voltage, and both outputs at zero acceleration are equal to the +2.5 volt reference. The sensitive axis is perpendicular to the bottom of the package, with positive acceleration defined as a force pushing on the bottom of the package.
      The Model 1210 has a wide range of application.Aspects of COMMERCIAL:Automotive,Air Bags,Active Suspension,Adaptive Brakes,Security Systems,Shipping Recorders and Appliances.Aspects of INDUSTRIAL:Vibration Monitoring,Vibration Analysis,Machine Control,Modal Analysis,Robotics,Crash Testing and Instrumentation.
      Absolute maximum ratings of Model 1210 is as follows:(1)Case Operating Temperature:-55 to +125;(2)Storage Temperature:-55 to +125;(3)Acceleration Over-range:2000g for 0.1 ms;(4)Voltage on VDD to GND:-0.5V to 6.5V;(5)Voltage on Any Pin (except DV) to GND:-0.5V to VDD+0.5V;(6)Power Dissipation:50 mW.
