Hi, 

I use LPS25H in my project. Based on the application note AN4450 page 13,

(example 1) when I configure the LPS25H to the mode that ODR is 25 Hz,  pressure average 512, temperature average 64 (register 0x20 is 0xC0, register 0x10 is 0x0F), the current is 690uA. This value is similar to the result in the application note.  

However,
(example 2)In the application note, the current is 26.4uA when ODR is 1 Hz, pressure average 512, temperature average 64. However, on my board, when I configure the LPS25H into the same mode (register 0x20 is 0x90, register 0x10 is 0x0F), the current is about 390uA. Why?
