(LIS3DH) What will be the slave address if the SDO/SA0 neither wired to VSS nor GND?

[DJi.1]

I have a board that uses LIS3DH. Unfortunately I find the SDO/SA0 pin does NOT wire to VSS or GND. In this case, what would be the Slave ADdress(SAD)?

In the spec it says 001100xb and the 'x' is either 1 or 0 when connected to VSS or GND. But no clue on my case.

Thanks,

How about reading pin description in the datasheet?

No content in the datasheet about my case

[Piranha]

Table 2. Pin description

7(1)

SDO / SA0

SPI serial data output (SDO) / 2C less significant bit of the device address (SA0)

1. SDO/SA0 pin is internally pulled up. Refer to Table 3 for the internal pull-up values (typ.).

Table 3. Internal pull-up values (typ.) for SDO/SA0 pin

So this is not a content?

Got it. That makes sense. Thanks a lot!​

When connecting SA0 to GND, the current will flow from VDD through internal pull-up to GND. From Table 3.: 3,6 V / 20,4 kOhm = 176 uA. Connecting SA0 to VDD or leaving pin unconnected should be the least current consuming option.

Got it. Thanks a lot.​
