Figure 1: Power budget
Although power consumption is the product of operating voltage (Vcc) multiplied by the current consumption (Icc), current consumption is usually the only parameter considered when describing the power characteristics of a chip. This is a mistake, because decreasing the operating voltage directly reduces

Figure 1: Development of Converged Network Adapter ASICs
Wouldn’t it be nice to save 25% to 30%, or even more, in circuit board power dissipation in your next design?
While for some designs such a savings would just be nice to have, for others it’s a necessity to make the design competitive using the latest high performance integrated circuits.

Figure 1: Isolating power & ground rails for sensitive data converters, amplifiers & references from other high current power paths improves signal resolution & reliability
Properly implemented, galvanic isolation is an effective defense against disturbances in the ground plane often referred to as ground loops, which occur as a result of varying electrical potentials.
Physical limitations require that electrical components on a PCB connect to the ground
