Overview
The BUF602IDR from Texas Instruments is a high-speed, closed-loop buffer designed for a wide range of applications requiring high-frequency signal buffering. This component is notable for its wide bandwidth of 1000 MHz and a high slew rate of 8000 V/µs, making it ideal for applications involving very high-frequency signals.
The BUF602IDR is available in both SO-8 and SOT23-5 surface-mount packages, catering to different footprint requirements. It supports flexible supply ranges, including ±1.4V to ±6.3V dual supplies and +2.8V to +12.6V single supply, and features an optional mid-supply reference buffer to reduce the need for external components.
