Part Number: LM26480

Hi team,

LM26480's datasheet mentions the enable signal needs 8ms delay from Vin.

What will be happened if it's violated?

In order for the LM26480 to initialize properly, TI requires that the enables be asserted high 8ms minimum after the bias supply for the device is stable. Adding a 1uF capacitor as you describe is a good approach. Not adhering to the delay time may cause unexpected behavior in the operation of the device.
