## Sensor Comparison Tables

See Also our [[Magnetometer|MagnetometerLv2]] Page or the [[Inertial Measurement Unit|InertialMeasurementUnit]] page

[[!toc levels="6"]]

<a name="DefInterval"></a>
Note, some of the table entries below use interval notation (min,typ,Max)

Examples

 > **(,5,10)** Typical = 5, Maximum = 10

 > **(3,5)**  minimum = 3, Maximum = 5

Non-interval values are typical.

### Accelerometers

Notes for the accelerometer table

The table has been roughly ordered by a dynamic range figure of merit, defined here as full-scale range divided by noise density.

The LIS2L02AQ3 and LIS344ALH have two different selectable full scale ranges.
Specifications for both ranges are given is adjacent rows.

Despite note 10 in the datasheet, the bandwidth of LIS2L02AQ3 appears to be un-specified.
Bandwidth has been estimated as (resonant freq.)/10.

Like the LIS2L02' the LIS3LV02DQ has two different selectable full scale ranges,
and therefore is given two rows in the table.

The LIS3LV02DQ gives a resolution figure of 1 milligee @ 40 Hz for the +/-2 gee span.
By simple division by the square root, the noise figure is 158 &mu;gee as given in the table.
The datasheet does not appear to give a noise density specification.

The ADXL330 and LIS344ALH are 3-axis accelerometers, but the z axis specification is markedly different from the xy axes. Therefore the xy and z specs are split into two rows in the table.

The ADIS16xxx series are standalone acquisition systems on a chip. I don't think they meet the requirements of our project.

The ADXL278 comes in variants with differing maximum gee ranges. The available ranges are +/-35, +/-50, and +/-70 gee. The +/-70 gee range is only available on a single axis, the cross axis in this case is +/-35 gee. All other ADXL278 models have symmetric sensitivities.

At least the ADXL278 series and the ADXL78 series have part codes that don't include their base numbers. For instance the +/-35gee version of the ADXL278 has the part number AD22284. This brain-deadness has been ignored in the table.
