1 RANGE Range Selection Pin. Set this pin to ground to select the ±10 g range, or set this pin to V to select the DDIO ±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. 3 ST2 Self Test Pin 2. This pin activates the electromechanical self test actuation. 4 TEMP Temperature Sensor Output. 5 V Digital Interface Supply Voltage. DDIO 6 V Digital Ground. SSIO 7 STBY Standby or Measurement Mode Selection Pin. Set this pin to ground to enter standby mode, or set this pin to V to enter measurement mode. DDIO 8 V Digital Supply. This pin requires a decoupling capacitor. If V connects to V , supply the voltage to this 1P8DIG SUPPLY SS pin externally. 9 V Analog Ground. SS 10 V Analog Supply. This pin requires a decoupling capacitor. If V connects to V , supply the voltage to this 1P8ANA SUPPLY SS pin externally. 11 V Supply Voltage. When V equals 2.25 V to 3.6 V, V enables the internal LDO regulators to generate SUPPLY SUPPLY SUPPLY V and V . For V = V , V and V are externally supplied. 1P8DIG 1P8ANA SUPPLY SS 1P8DIG 1P8ANA 12 X X-Axis Output. OUT 13 Y Y-Axis Output. OUT 14 Z Z-Axis Output.
