Driving Power-down and self-test signals
The board allows the control of the Power-down and Self-test signals through the use of test
points (marked J3 and J7, respectively) and jumpers.
Power-down
When the jumper is removed from J3 (Power-down,
normal mode, otherwise it is in power-down mode.
Self-test
When the jumper is removed from J7 (Self-Test,
disabled. In order to activate the self-test feature the jumper must be inserted into J7.
When this function is activated the seismic mass of the sensor is moved by means of an
electrostatic test-force, simulating a definite input acceleration. Under these conditions the
sensor outputs will exhibit a voltage change in their DC levels as specified in the datasheet
of the LIS302SG sensor.
Multiplexed output
The device provides an embedded multiplexer to allow the redirection of either the analog
output signals Vout
operation with a single channel A/D converter. Output selection can be achieved through
jumpers J6 and J9 (S0 and S1,
