1. An apparatus, comprising:
a package terminal array comprising a plurality of terminals, wherein a spacing between adjacent terminals is less than 0.5 mm;
a first high-voltage circuit configured to output a first signal to a first terminal of the package terminal array that may exceed 15 volts;
a second high-voltage circuit configured to output a second signal to a second terminal of the package terminal array that may exceed 15 volts; and
a low-voltage circuit coupled to a third terminal of the package terminal array and positioned between the first high-voltage circuit and the second high-voltage circuit, wherein the low-voltage circuit comprises circuitry organized in columns oriented along an axis and the columns having a width defined by a fraction of the spacing of the package terminal array,
wherein:
the fraction is a ratio of a positive integer number less than or equal to twelve,
the first high-voltage circuit and the second high-voltage circuit are positioned symmetrically around the axis, and
the first terminal and the second terminal are located at an edge of the package terminal array.
