... The supply voltage should be kept as low as possible, while the transformer ratio should be selected so that the peak voltage required from the EL1503A is close to the maximum available output swing. There is a trade of however with the selection of transformer ratio. As the ratio is increased, the receive signal available to the receivers is reduced ...

... A separate application note details the 24 Ld QFN PCB design considerations. Single Supply Operation The EL1503A can also be powered from a single supply voltage. When operating in this mode, the GND pins can still be connected directly to GND. To calculate power dissipation, the equations in the previous section should be used, with V equal to half the supply rail ...

... EL1503A drive amplifiers. As the supply current is reduced, the EL1503A will start to exhibit slightly higher levels of distortion and the frequency response will be limited. The 4 power modes of the EL1503A are set up as shown in the table 2. TABLE 2. POWER MODES of the EL1503A ...
