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 ?
Correct, you just need a bias inductor, as described in the Basic Connections schematic (Figure 26). With a supply voltage of 5V, this will result in a bias current of approx. 90mA
