9.1.1 Output Common-Mode Voltage

The output common-mode voltage pin sets the dc output voltage of the THS413x. A voltage applied to the VOCM pin from a low-impedance source can be used to directly set the output common-mode voltage. If left floating, then the VOCM pin defaults to the mid-rail voltage, defined as:

Equation 1. ( V C C+ ) + ( V C C– ) 2

To minimize common-mode noise, connect a 0.1-µF bypass capacitor to the VOCM pin. Output common-mode voltage causes additional current to flow in the feedback resistor network. This current is supplied by the output stage of the amplifier; therefore, additional power dissipation is created. For commonly-used feedback resistance values, this current is easily supplied by the amplifier. The additional internal power dissipation created by this current can be significant in some applications and can dictate the use of the HVSSOP package to effectively control self-heating.
