Other Parts Discussed in Thread: LMP91000
I have used one LMP91000 in circuit and tied the MENB pin to ground. But, when I am doing some measurements I find a high noise level which I suspect is due to some digital clock circuit no matter there is no clock signal provided on the SCL pin. .
It is mentioned in the dataseheet that when just one LMP91000 is present on the I2C bus the MENB can be tied to ground (low logic level). But, by doing so aren't we keeping the I2C Interface always active which can consume power and keep the I2C Interface analog modules active which can introduce some noise? Can you please describe the decoder circuit used in the I2C module interface?
