DESCRIPTION
The Model 1010 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 sigma-delta A/D converter. 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 (1010-TST) is also available which lists the measured bias, scale
factor, linearity, operating current and frequency response.
OPERATION
The Model 1010 produces a digital pulse train in which the density of pulses (number of pulses per second) is
proportional to applied acceleration. It requires a single +5 volt power supply and a TTL/CMOS level clock of 100kHz-
1MHz. The output is ratiometric to the clock frequency and independent of the power supply voltage. Two forms of
digital signals are provided for direct interfacing to a microprocessor or counter. 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.
External digital line drivers can be used to drive long cables or when used in an electrically noisy environment.
