Description

1

RANGE

Range Selection Pin. Set this pin to ground to select the ±10 g range, or set this pin to VDDIO to select the

±20 g or ±40 g range. This pin is model dependent (see the Ordering Guide section).

2

ST1

Self Test Pin 1. This pin enables self test mode. This pin must be forced low when not in self test mode.

3

ST2

Self Test Pin 2. This pin activates electromechanical self test actuation. This pin must be forced low when not

in self test mode.

4

TEMP

Temperature Sensor Output.

5

VDDIO

Digital Interface Supply Voltage.

6

VSSIO

Digital Ground.

7

STBY

Standby or Measurement Mode Selection Pin. Set this pin to ground to enter standby mode, or set this pin

to VDDIO to enter measurement mode.

8

V1P8DIG

Digital Supply. This pin requires a decoupling capacitor. If VSUPPLY connects to VSS, supply the voltage to this

pin externally.

9

VSS

Analog Ground.

10

V1P8ANA

Analog Supply. This pin requires a decoupling capacitor. If VSUPPLY connects to VSS, supply the voltage to this

pin externally.

11

VSUPPLY

Supply Voltage. When VSUPPLY equals 2.25 V to 3.6 V, VSUPPLY enables the internal LDO regulators to generate

V1P8DIG and V1P8ANA. For VSUPPLY = VSS, V1P8DIG and V1P8ANA are externally supplied.

12

XOUT

X-Axis Output.

13

YOUT

Y-Axis Output.

14

ZOUT

Z-Axis Output.
