ADL5610/1 v.s. ADL5544/5 not need to limit the supply current?

Hi all,

Following is datasheet comment,

"The only external components required are the input/output ac coupling capacitors, power supply decoupling capacitors, and dc bias inductor."

The general gain block amps need to dc bias inductor and/or dc bias resistor to select dc bias resistor to achieve the supply current.

Is it correct, not need to limit the supply current, with dc bias resistor ?

Best regards,

sss

    Thank you for reply.

    I am slightly confused.

    Please let me know if my understanding is Correct.

    90mA @ 5.0V is spec over, 70(max) mA @ 5.0V ?

    is it incorrect?

    In the datasheet spec.,

    POWER INTERFACE VPOS
    Supply Voltage:4.75(min) 5(typ) 5.25(max) V
    Supply Current:56(typ) 70(max) mA
    vs. Temperature:−40°C ≤ TA ≤ +85°C −6(typ) mA
