The FXLN83xxQ Xtrinsic accelerometers are 3-axis high-performance that provide

analog capability for industrial, medical and tamper detection applications. These

accelerometers can also be used for vibration detection for battery operated

applications with extended temperature range and bandwidth options. Additionally,

these scalable accelerometers provide interface compatibility and simplicity for low-

voltage microcontrollers (MCUs).

These new FXLN83xxQ analog accelerometers expand Freescale’s portfolio, adding

best-in-class analog performance. The integrated regulator simplifies low-voltage

implementation and provides isolation from injected noise. Fixed zero-g offset provides

improved signal integrity even in poor supply environments. Smart system power

management is achieved with the accelerometers fast turn on time. The extended

temperature range to 105°C is ideal for machine control and direct sun applications.
