, the SOT-23 package only requires one-third the board space of the standard 8-pin
SOIC package. This ultra-small package allows designers to place single amplifiers very close to the signal
source, minimizing noise pick-up from long PCB traces. TI has also taken special care to provide a pinout that
is optimized for board layout (see Figure 2). Both inputs are separated by GND to prevent coupling or leakage
paths. The OUT and IN− terminals are on the same end of the board to provide negative feedback. Finally, gain
setting resistors and decoupling capacitor are easily placed around the package.
