3.10 J: 2 × X2QFN (RUG)

As shown in Figure 3-10, two dual-channel X2QFN (RUG) devices can be adapted to a quad-channel SOIC footprint.

This X2QFN adapter board has three additional pads for a 0402 resistor to allow the shutdown (SD) pins to be tied to either V+ or V-. These pads are provided since many op amps require an external pull-up or pull-down resistor to bring the op amp out of shutdown.
