Supply Current Measurement Mode 100 Hz ODR (50 Hz bandwidth)6 Normal Operation 1.8 µA Low Noise Mode 3.3 µA Ultralow Noise Mode 13 µA Wake-Up Mode 0.27 µA Standby 0.01 µA Power Supply Rejection Ratio (PSRR) CS = 1.0 µF, RS = 100 Ω, CIO = 1.1 µF, input is 100 mV sine wave on VS Input Frequency 100 Hz to 1 kHz −13 dB Input Frequency 1 kHz to 250 kHz −20 dB Turn-On Time 100 Hz ODR (50 Hz bandwidth) Power-Up to Standby 5 ms Measurement Mode Instruction to 4/ODR Valid Data TEMPERATURE SENSOR Bias Average @ 25°C 350 LSB Standard Deviation 290 LSB Sensitivity Average 0.065 °C/LSB Standard Deviation 0.0025 °C/LSB Sensitivity Repeatability ±0.5 °C Resolution 12 Bits ENVIRONMENTAL Operating Temperature Range −40 +85 °C 1 All minimum and maximum specifications are guaranteed. Typical specifications may not be guaranteed. 2 Cross axis sensitivity is defined as coupling between any two axes. 3 −40°C to +25°C or +25°C to +85°C. 4 Different supplies and measurement range cause different offset. 5 Self test change is defined as the output change in g when self test is asserted. Different supplies cause different self test changes. These limits apply to the specific test conditions stated in Table 1. For variations over the full Vs supply range, see Table 22. 6 Refer to Figure 30 for current consumption at other bandwidth settings. Rev.
