10.3 Logic Levels Diagram

The figure below depicts a sample circuit with a third party pressure sensor attached to the auxiliary I2C bus.

It shows logic levels and voltage connections. Note: Actual configuration will depend on the auxiliary sensors

used.

I/O Levels and Connections

Notes:

1. The IO voltage levels of ES_DA and ES_CL are set relative to VDD.

2. Third-party auxiliary device logic levels are referenced to VDD. Setting INT1 and INT2 to open drain

configuration provides voltage compatibility when VDD ≠ VLOGIC. When VDD = VLOGIC, INT1 and

INT2 may be set to push-pull outputs, and external pull-up resistors are not needed.

3. All other MPU-9150 logic IO is always referenced to VLOGIC.
