LM48580: change the volume up and down in the part number LM48580TLX/NOPB

Hi Chintan,

The gain in LM48580 is controlled by Gain pin, 3 options exist: Float, GND or VDD.
Refer to Data Sheet Section 13.3.5: LM48580 Boomer Audio Power Amplifier Series High Efficiency Class H, High Voltage, Haptic Piezo Actuator / Ceramic Speaker Driver datasheet (Rev. B)

If need a smaller gain/volume step, it's better to adjust the amplitude of the input signal.
