BUF634A Datasheet High-Speed Buffer

Manufacturer: Texas Instruments

General Description

The BUF634A device is a high-performance, highfidelity, open-loop buffer that is capable of driving 250 mA of output current.

The BUF634A is a 36-V device with an adjustable bandwidth of 35 MHz to 210 MHz, which is accomplished by varying the value of an external resistor between the V– and BW pins.

V+ 1 kQ 1 kQ The BUF634A device can be used as a standalone open-loop driver, or used inside the feedback loop of a precision op amp to provide both high-precision and large output current drive with improved capacitive load drive.
