Hi

we are using P/N: LMH6554LEE in our design, please find the below image for reference and can you share the maximum input supply current for +2.5V and -2.5V.

Thanks in advance.

Regards

    Hello Haritha,

    You can view the Typical Characteristics curves for Max and Min Iout for a selected Vout.  The supply current has a maximum rating in the Electrical Characteristics table.  This rating is a typical value of 52mA with a maximum of 57mA at 25C.  At extreme temperatures the typical can increase to 60mA. 

    In your schematic diagram there is mention of LMH6554 operating at 60mA with an additional 10mA for a load.  The 60mA typical rating is for extreme temperature and an open (infinite) load.  You can observe ratings for short-circuit current and output current in these tables also. 

    At 25C and being powered on with no signal, the amplifier should not be drawing 60mA, but rather close to 52mA. 

    Best,

    Alec
