PROPRIETARY TECHNOLOGY

These high-performance silicon micromachined linear accelerometers and

inclinometers consist of a sensor element and an ASIC packaged in a

5x5x1.2mm Dual Flat No-lead (DFN). The sensor element is fabricated from

single-crystal silicon with proprietary Deep Reactive Ion Etching (DRIE)

processes, and is protected from the environment by a hermetically-sealed

silicon cap at the wafer level.

The KXD94 series is designed to provide a high signal-to-noise ratio with

excellent performance over temperature. These sensors can accept supply

voltages between 2.5 – 5.25V.

Sensitivity is factory programmable for

applications requiring from ±5.0g to ±15.0g ranges. Sensor bandwidth is

user-definable.

The sensor element functions on the principle of differential capacitance.

Acceleration causes displacement of a silicon structure resulting in a

change in capacitance.

An ASIC, using a standard CMOS manufacturing

process, detects and transforms changes in capacitance into an analog out-

put voltage, which is proportional to acceleration. The sense element de-

sign utilizes common mode cancellation to decrease errors from process

variation, temperature, and environmental stress.
