put transistors into saturation and improve the output voltage swing for extra efficient operation when

required. When close swings to the supply rails is not required the +VBOOST and +VS pins must be strapped

together as well as the –VBOOST and –VS pins. The boost voltage pins must not be at a voltage lower than the

VS pins.

COMPENSATION

Compensation is internally fixed for a gain of 3 or more and is not adjustable by the user. The PA52 there-

fore is not unity gain stable.

POWER SUPPLY BYPASSING

Proper and sufficient power supply bypassing is crucial to proper operation of the PA52. Bypass the +Vb

and -Vb supply pins with a minimum 0.1µF ceramic capacitors directly at the supply pins. On the +Vs and -Vs

pins use a combination of ceramic and electrolytic capacitors. Use 1µF ceramic capacitors and an electrolytic

capacitor at least 10µF for each amp of output current required.
