The Model 1521 is a low-cost, general-purpose integrated MEMS accelerometer for use in zero to medium frequency instrumentation applications that require extremely low noise and reliable long-term stability. 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 very insensitive to temperature changes and gradients. Each device is marked with a serial number on its top and bottom surfaces for traceability. An optional calibration test sheet (1521-TST) is also available which lists the measured bias, scale factor, linearity, operating current and frequency response.

The model 1521 sensitive axis is perpendicular to the bottom of the package, with positive acceleration resulting from a positive force pushing on the bottom of the package. The seismic center is located on a centerline through the dual sense elements and halfway between them. The internal electronics effectively cancel any errors due to rotation. Two reference voltages, +5.0 and +2.5 volts (nominal), are required; scale factor is ratiometric to the +5.0 volt reference voltage relative to GND, and both outputs at zero acceleration are nominally 80 mV below the +2.5 volt b.
The Model 1521 produces a differential +/-4 volts output voltage or single ended mode, 0.5 鈥� 4.5 volts full scale, the value of which varies with acceleration as shown in the figures below.
