NOTE1: Rp are typically 4.7kâ¦ pullup resistors to VDD/VDDIO, per I2C specification. When

pin VDD/VDDIO is powered down, SDA and SCL will be driven low by internal ESD diodes.

NOTE2: Attach typical 4.7kâ¦ pullup resistor if INTN is defined as open-drain.

Figure 5. Typical Application Circuit For 3DOF Solution

In typical applications, the interface power supply may contain significant noise from external

sources and other circuits which should be kept away from the sensor. Therefore, for some

applications a lower-noise power supply might be desirable to power the VDD/VDDIO pin.
