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