1210L-005 Datasheet, PDF (2/6 Pages) List of Unclassifed Manufacturers – ANALOG ACCELEROMETER

Model 1210 Analog Accelerometer
SIGNAL DESCRIPTIONS
V_DD and GND (power): Pins (8,9,11,14) and (2,5,6,18,19) respectively. Power (+5 Volts DC) and ground.
AOP and AON (output): Pins 12 and 16 respectively. Analog output voltages proportional to acceleration. The AOP voltage
increases (AON decreases) with positive acceleration; at zero acceleration both outputs are nominally equal to the +2.5 volt
reference. The device experiences positive (+1g) acceleration with its lid facing up in the earth’s gravitational field. Either
output can be used individually or the two outputs can be used differentially but differential mode is recommended for both
lowest noise and highest accuracy operation. Voltages can be measured ratiometrically to VR for good accuracy without
requiring a precision reference voltage. (See plot.)
DV (input): Pin 4. Deflection Voltage. Normally left open. A test input that applies an electrostatic force to the sense element,
simulating a positive acceleration. The nominal voltage at this pin is ½ V_DD. DV voltages higher than required to bring the
output to positive full scale may cause device damage.
VR (input): Pin 3. Voltage Reference. Tie directly to V_DD for ratiometric measurements or to a +5V reference for better absolute
accuracy. A 0.1µF bypass capacitor is recommended at this pin.
2.5 Volt (input): Pin 17. Voltage Reference. Tie to a resistive voltage divider from +5 volts or to a +2.5 volt reference voltage.
PERFORMANCE - by Model: V_DD=V_R=5.0 VDC, T_C=25EC.
