POWER SUPPLIES
As shown in Figure 52, the LMH6514 has a number of options for power supply connections on the output pins.
Pin 3 (V
CC
) is always connected. The output stage can be connected as shown in Figure 53, Figure 54, and
Figure 55. The supply voltage range for V
CC
is 4V to 5.25V. A 5V supply provides the best performance while
lower supplies will result in less power consumption. Power supply regulation of 2.5% or better is advised.
Of special note is that the digital circuits are powered from an internal supply voltage of 3.3V. The logic pins
should not be driven above the absolute maximum value of 3.6V. See the DIGITAL CONTROL section for
details.
