Description

The BUF634 is a high speed unity-gain open-loop buffer recommended for a wide range of applications.

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/s 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 of BUF634 is fully protected by internal current limit and thermal shut-down making it rugged and easy to use.

The BUF634 is available in a variety of packages to suit mechanical and power dissipation requirements.

Types include 8-pin DIP, SO-8 surface-mount, 5-lead TO-220, and a 5-lead DDPAK surface-mount plastic power package.
