Notes:
1. Current varies with Output Data Rate (ODR) as shown in Figure 2, types and number of enabled digital engines, the average
filter control settings, and VDD. Measured with OWUF<2:0> = 0, OSA<3:0> = 0, AVC<2:0> = 1, LPSTPSEL = 1.
2. For I
2
C communication, this assumes a minimum 1.5kΩ pull-up resistor on SCL and SDA pins.
3. Start up time is from PC1 set to valid outputs. Time varies with ODR, Power Mode, and FSTUP bit setting (see Figure 1).
4. Power up time is from VDD valid to device boot completion.
5. Typical values. ODR is user-selectable via I
2
C or SPI. See ODCNTL register for details.
6. Refers to accelerometer’s raw output data. Additional bandwidth control is available using the Advanced Data Path (ADP)
engine.
7. Measured with RMS_AVC<2:0> = 1, OADP<3:0> = 0, LPSTPSEL = 0.
