MMA1260D

Freescale Semiconductor Technical Data MMA1260D Rev. 1, 10/2004 Low G Micromachined Accelerometer The MMA series of silicon capacitive, micromachined accelerometers features signal conditioning, a 2--pole low pass filter and temperature compensation. Zero--g offset full scale span and filter cut--off are factory set and require no external devices. A full system self--test capability verifies system functionality. Features Integral Signal Conditioning Linear Output 2nd Order Bessel Filter Calibrated Self--test EPROM Parity Check Status Transducer Hermetically Sealed at Wafer Level for Superior Reliability Robust Design, High Shock Survivability Typical Applications Vibration Monitoring and Recording Appliance Control Mechanical Bearing Monitoring Computer Hard Drive Protection Computer Mouse and Joysticks Virtual Reality Input Devices Sports Diagnostic Devices and Systems MMA1260D MMA1260D: Z AXIS SENSITIVITY MICROMACHINED ACCELEROMETER ±1.5g 16 9 1 8 16 LEAD SOIC CASE 475--01 Pin Assignment VSS VSS VSS VOUT STATUS VDD VSS ST 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 N/C N/C N/C N/C N/C N/C N/C N/C ORDERING INFORMATION Device MMA1260D Temperature Range --40 to +105°C Case No. Case 475--01 Package SOIC--16 SIMPLIFIED ACCELEROMETER FUNCTIONAL BLOCK DIAGRAM VDD G--CELL SENSOR INTEGRATOR GAIN FILTER TEMP COMP & GAIN VOUT ST SELF--TEST CONTROL LOGIC & EPROM TRIM CIRCUITS OSCILLATOR CLOCK GEN.
