Table 4. Mechanical characteristics
• Analog acceleration output pin loading = 3.3 nF capacitors on X and Y axes, with 8.2 nF capacitor on Z axis (HBW
configuration)
• Analog acceleration output pin loading = 9.1 nF capacitors on X, Y and Z axes (LBW configuration)
• No analog acceleration output pin loading other than external BW setting capacitor
• No BYP pin loading other than bypass capacitor and 150 μA DC current draw through resistive divider.
1. Limits verified by characterization only.
2. High and Low Bandwidth modes are configured in non-volatile Memory (NVM) at the factory

Notes:
Test conditions (unless otherwise noted):
• V
DD
= 2.8 V
• Output load = 3.3 nF capacitors on X and Y axes, with 8.2 nF capacitor on Z axis (HBW configuration)
• Output load = 9.1 nF capacitors on X, Y and Z axes (LBW configuration)
• Output loading other than external capacitor: high impedance
• No electrical loading on BYP pin other than output capacitor and 150 μA (max)
• DC output current for ADC reference input
• T = 25°C, ±2 g range (for ±2/8 g product), ±4 g range (for ±4/16 g product)
1. Limits verified by characterization only.
2. Apply VDD first. Then, Turn-on time is defined by the delay between when the EN pin is set to high and the time at
which a pin's output value reaches 90% of its final value.
3. g-Select pin transition from high to low. Time for output value to reach 90% of final value.
