DESCRIPTION
The Model 1210 is a low-cost, integrated accelerometer for use 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.
OPERATION
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.
