250-mA high-speed buffer - see BUF634A for upgraded version

The BUF634 is a high-speed,

unity-gain, open-loop buffer recommended for a wide range of applications. The

BUF634 can be used inside the feedback loop of op amps to increase output current,

eliminate thermal feedback, and improve capacitive load drive.

For low-power applications, the BUF634

operates on 1.5mA quiescent current with 250mA output, 2000V/µs slew rate, and 30MHz

bandwidth. Bandwidth can be adjusted from 30MHz to 180MHz by connecting a resistor

between V– and the BW pin.

Output circuitry is fully protected by

internal current limit and thermal shutdown, making the device rugged and easy to

use.

The BUF634 is available in a variety

of packages to meet mechanical and power-dissipation requirements. Types include

SOIC‑8 surface-mount, 5‑lead TO‑220, and a 5‑lead TO‑263 (DDPAK) surface-mount

plastic power packages.
