LMP91000: How to find LMP91000 I2C ADDRESS ?

Hieu Nguyen63

Part Number: LMP91000

Hello everyone,

I have just read the datasheet of LMP91000.

I also read some sample code and the define value of LMP91000 I2C address is 0x48.

But I cannot find any information about I2C device address from datasheet.

Anyone can help me ?

Thank you very much !

Hi Hieu,

The I2C address is on page 20 of the datasheet, last sentence of section 7.5.1.

Thanks,
Ren

But all LMP91000 i2c address are 0x48 ? How to interface with multiple modules using LMP91000 IC inside ?
