Offset error

SCA110 (5V) Accelerometers are ratiometric; Offset and Sensitivity are proportional to supply

voltage.

Output swing 0.5 - 4.5 V with nominal supply voltage.

Measuring direction is perpendicular to the mounting plane (see Note 10). Zero is deﬁned with

no acceleration and the device mounted in the prescribed mounting plane (see Note 10 and

pictures page 2).

Sensitivity speciﬁed as [Vout (+1g) - Vout(-1g)] / 2 [V/g].

Zero point error speciﬁed as (Vout (+0g) - Vdd/2) / Vsens [g] (room temp. error included);

Vsens = Nominal sensitivity.

Sensitivity error speciﬁed as { [Vout(+1g)-Vout(-1g)] / 2 - Vsens} / Vsens x 100% Vsens =

Nominal sensitivity.

VTI Technologies reserves the right to modify this speciﬁcation without prior to notice.

Output has true DC (0Hz) response.

The cross-axis sensitivity determines how much acceleration, perpendicular to the measuring

axis, couples to the output. The total cross-axis sensitivity is the geometric sum of the

sensitivities of the two axes, which are perpendicular to the measuring axis.

Offset measuring direction in ﬁgures (see picture page 2)

Supply voltage noise also couples to the output, due to the ratiometric (output proportional to

supply voltage) nature of the accelerometer.
