Mechanical and electrical specifications

Self Test
allows to test the mechanical and electric part of the sensor, allowing the seismic
mass to be moved by means of an electrostatic test-force. The Self Test function is off when
the ST pin is connected to GND. When the ST pin is tied at Vdd an actuation force is applied
to the sensor, simulating a definite input acceleration. In this case the sensor outputs will
exhibit a voltage change in their DC levels which is depending on the supply voltage through
the device sensitivity. When ST is activated, the device output level is given by the algebraic
sum of the signals produced by the acceleration acting on the sensor and by the
electrostatic test-force. If the output signals change within the amplitude specified inside
Table 3
, than the sensor is working properly and the parameters of the interface chip are
within the defined specification.
Output impedance
describes the resistor inside the output stage of each channel. This
resistor is part of a filter consisting of an external capacitor of at least 2.5nF and the internal
resistor. Due to the resistor level, only small inexpensive external capacitors are needed to
generate low corner frequencies. When interfacing with an ADC it is important to use high
input impedance input circuitries to avoid measurement errors. Note that the minimum load
capacitance forms a corner frequency close to the resonance frequency of the sensor. In
general the smallest possible bandwidth for a particular application should be chosen to get
the best results.
