Product Summary

The BUF634U 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 BUF634U operates on 1.5mA quiescent current with 250mA output, 2000V/μs slew rate and 30MHz bandwidth. Band-width can be adjusted from 30MHz to 180MHz by connecting a resistor between V– and the BW Pin. The applications of the BUF634U include valve driver solenoid driver, op amp current booster, line driver, headphone driver, video driver, motor driver, test equipment and ate pin driver.
