Texas Instruments XBUF634AIDRBT
The BUF634A is a high-performance, high-fidelity, open-loop buffer capable of driving 250mA of output current. The BUF634A is a 36-V device with bandwidth adjustable from 35 MHz to 210 MHzby varying the value of an external resistor between the V– and BW pins. The BUF634A can be used asa standalone open-loop driver, or inside the feedback loop of a precision op amp to provide bothhigh-precision as well as large output current drive with improved capacitive load drive.
For low-power applications, the BUF634A operates on a 1.5-mA quiescent current with a250-mA output, 3750-V/µs slew rate, and 35-MHz bandwidth. The device consumes 8.5-mA quiescentcurrent in wide-bandwidth mode with a 210-MHz bandwidth. The BUF634A is fully protected by aninternal current limit in its output stage and by thermal shutdown, making the device rugged andeasy to use.
The BUF634A is rated to function over the extended industrial temperature range of –40°Cto +125°C. The BUF634A comes in three packages: D (SOIC), DRB (VSON), and DDA (HSOIC). The DRB(VSON) and DDA (HSOIC) packages have excellent thermal performance resulting from the thermal padon the bottom side. The DRB package comes in a very small form factor of 3.0 mm × 3.0 mm, makingthe device a very suitable option for portable and size-constrained applications.
