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 1.5m A quiescent current with 250m A 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.
