Description
General part information
BUF634A Series
The BUF634A device is a high-performance, high-fidelity, 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.
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.
For low-power applications, the BUF634A device operates on a 1.5-mA quiescent current with a 250-mA output, 3750-V/µs slew rate, and 35-MHz bandwidth. The device consumes 8.5-mA quiescent current in wide-bandwidth mode with a 210-MHz bandwidth. The BUF634A is fully protected by an internal current limit in its output stage and by thermal shutdown, making the device rugged and easy to use.
