Otherwise, it stays Low. Interrupt Signal 1 When all X, Y, Z outputs go below set threshold (0.4G), this terminal outputs High. 4 INT1 *1 Otherwise, it stays Low. 5 T OUT Temperature Sensor Output 6 VDD Power Supply 7 LCA Connect capacitor for internal circuit. 8 X OUT Analog Output X 9 Y OUT Analog Output Y 10 Z OUT Analog Output Z *1：Interrupt thresholds are set up individually at our factory. *2：Please leave A～D unconnected. 1/29/2007 HOKURIKU *Details are subject to change without notice. 1 Piezoresisitive 3-Axis Acceleration Sensor HAAM-327A ■Outline & Dimensions Rating Item Min Operating Condition Storage Temperature Range Operating Temperature Range Supply Voltage Typ Max -40 -25 2.2 0.7 0.35 1 2 Supply Current Supply Current at Standby Mode Turn-on Time (at C=0.01µF) Shock Resistance Electrical Characteristics (Ta=25℃, Vdd=3.0V) Rated Acceleration Offset Voltage Offset Temperature Characteristics Sensitivity Linearity of sensitivity Sensitivity Temperature Characteristics Cross-Axis Sensitivity 85 75 3.6 1 0.5 5 5000 -3 1.425 -10 297 -1 -3 -5 3 1.575 10 363 1 3 5 500 250 1.5 330 DC Resonant Frequency Temperature Sensor Output (Vdd=3.0V) Offset Voltage Sensitivity Output Accuracy 1.5 10 -3 3 Unit Note ℃ ℃ V Ratiometric at Mode A, Vdd=3.0V at Mode B, Vdd=3.0V mA uA msec G Until it becomes 99％ G V %FS/G mV/G %FS %FS/G % Ratiometric against Supply Voltage ⊿ from 25℃ Ratiometric against Supply Voltage ⊿ from 25℃ at Mode A at Mode B Hz V Ratiometric against Supply Voltage mV/℃ Ratiometric against Supply Voltage for -25～75℃ ℃ ■Block Diagram VDD STANBY X Sensor Y Sensor Rout(32kΩ) X OUT Cx Rout(32kΩ) Y OUT Cy Rout(32kΩ) Z OUT Cz S/H Multiplexer Z Sensor Amplifier S/H Demultiplexer S/H EEPROM Rout(32kΩ) T Sensor GND T OUT S/H Calculation Logic LCA * (10nF) INT1 INT2 *Please connect 10nF (tentative value) capacitor to LCA for use. 1/29/2007 HOKURIKU *Details are subject to change without notice. 2
