Add To BomBUF634U General Description
The BUF634U is a high-speed buffer amplifier with a unity-gain bandwidth of 200 MHz. It is designed to provide high output current drive capability while maintaining low power consumption. The device operates on a supply voltage range of ±2.5V to ±18V and can deliver output currents up to ±250 mA.The BUF634U features a high slew rate of 2000 V/μs, allowing it to quickly respond to fast input signals. It also has a low input offset voltage of ±1 mV, ensuring accurate signal reproduction. The device is unity-gain stable and has a low harmonic distortion of -85 dB at 1 MHz.The BUF634U comes in a small, surface-mount SOIC package, making it suitable for space-constrained applications. It is ideal for use in audio equipment, instrumentation, and other high-speed signal processing systems that require high output current drive capability and low distortion.
