PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The BUF634A is intended for operation on supplies ranging from 4.5 V to 36 V (±2.25 V to ±18 V). At low power-supply conditions, such as ±2.25 V, the output swing may be limited. See the output voltage range specifications in the Electrical Characteristics tables for additional information. The BUF634A can be operated on single-sided supplies, split, and balanced bipolar supplies or unbalanced bipolar supplies. Operating from a single supply can have numerous advantages. With the negative supply at ground, the DC errors resulting from the –PSRR term can be minimized. Minimize the distance (< 0.1 in.) from the power-supply pins to high-frequency, 0.1-µF decoupling capacitors. A larger capacitor (10 µF typical) is used along with a high-frequency, 0.1-µF supply-decoupling capacitor at the device supply pins. For single-supply operation, only the positive supply has these capacitors. When a split-supply is used, use these capacitors from each supply to ground. If necessary, place the larger capacitors further from the device and share these capacitors among several devices in the same area of the PCB.
