Since we get into accelerometer discussions here I thought I'd post
some information I just received.

This is Revision zero.zero for a product under development so they can
change ANY specification at any time before this product comes to market.

Parts should be available late late late 1992 (That's like second quarter '93)

Analog Devices ADXL50 Monolithic Accelerometer with signal conditioning.

FEATURES:
  - Full-scale measurement range +/-50g
  - Self-test on digital command. (You give it a +5Vdc signal on the test
    pin and it electrostatically deflects the beam element and returns a
    -50g signal if it's working)
  - Single power supply of +5Vdc tp +24 Vdc
  - Output range 0.25 V to 4.75 V
  - Accuracy of span: 8% over -55 degrees C to +125 Degrees C (That's hot)
  - Uncommitted output amplifier for custom scaling and zero-g level adjustment
  - Programmable bandwidth: DC up to 1 kHz
  - Additional filtering: 2-Pole with external passive components
  - High shock survival: >2000 g Unpowered. (Two thousang g!)

APPLICATIONS:
  - Crash detection for airbag deployment and seatbelt retraction
  - Vibration analysis and cancellation
  - Measurement, Characterization and insturmentation. e.g. Crash dummies

GENERAL DESCRIPTION:
  The ADXL50 is a monolithic accelerometer which combines a polysilicon
  micromachined sensor with signal conditioning and signal processing
  circuitry. 
  It is capable of measuring both psitive and negative accelerations in 
  the +/- 50g range, offering a bandwidth of DC up to 1 kHz.
  The ADXL50 uses a capacitive measurement scheme. The analog output is
  directly proportional to acceleration, and is fully scaled, refrenced
  and temperture compensated resulting in high accuracy and linearity over 
  the automotive temperature range.
  A digitally commandable self-test mode allows the sensor beam to be
  electrostatically deflected at any time, producing an output voltage
  which corresponds to the -50g output of a healthy sensor beam.

  This comes in either a 10 pin metal can (9.4mm diameter and 4.7mm tall)
  or a 14 pin DIP

  Positive acceleration is defined so that the DIP moves in the plane of
  the package, toward the end of the package with the notch. (1 and 14 pins)
  Positive acceleration is defined so that the cylinder moves in the plane
  of it's pins towards the #10 pin. (I know you don't know where that is but
  it's "sideways")
